Mozilla Network Security Services (NSS) before 3.23, as used in Mozilla Firefox before 47.0, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unknown vectors.

Mozilla Firefox was updated to the Firefox ESR release 45.9. Mozilla NSS was updated to support TLS 1.3 (close to release draft) and various new ciphers, PRFs, Diffie Hellman key agreement and support for more hashes. Security issues fixed in Firefox (bsc#1035082)

  - MFSA 2017-11/CVE-2017-5459: Buffer overflow in WebGL     Mozilla NSS was updated to 3.29.5, bringing new features     and fixing bugs :

  - Update to NSS 3.29.5 :

  - MFSA 2017-11/CVE-2017-5461: Rare crashes in the base 64     decoder and encoder were fixed.

  - MFSA 2017-11/CVE-2017-5462: A carry over bug in the RNG     was fixed.

  - CVE-2016-9574: Remote DoS during session handshake when     using SessionTicket extention and ECDHE-ECDSA     (bsc#1015499).

  - requires NSPR >= 4.13.1

  - Update to NSS 3.29.3

  - enables TLS 1.3 by default

  - Fixed a bug in hash computation (and build with GCC 7     which complains about shifts of boolean values).
    (bsc#1030071, bmo#1348767)

  - Update to NSS 3.28.3 This is a patch release to fix     binary compatibility issues.

  - Update to NSS 3.28.1 This is a patch release to update     the list of root CA certificates.

  - The following CA certificates were Removed CN = Buypass     Class 2 CA 1 CN = Root CA Generalitat Valenciana OU =     RSA Security 2048 V3

  - The following CA certificates were Added OU = AC RAIZ     FNMT-RCM CN = Amazon Root CA 1 CN = Amazon Root CA 2 CN     = Amazon Root CA 3 CN = Amazon Root CA 4 CN = LuxTrust     Global Root 2 CN = Symantec Class 1 Public Primary     Certification Authority - G4 CN = Symantec Class 1     Public Primary Certification Authority - G6 CN =     Symantec Class 2 Public Primary Certification Authority
    - G4 CN = Symantec Class 2 Public Primary Certification     Authority - G6

  - The version number of the updated root CA list has been     set to 2.11

  - Update to NSS 3.28 New functionality :

  - NSS includes support for TLS 1.3 draft -18. This     includes a number of improvements to TLS 1.3 :

  - The signed certificate timestamp, used in certificate     transparency, is supported in TLS 1.3.

  - Key exporters for TLS 1.3 are supported. This includes     the early key exporter, which can be used if 0-RTT is     enabled. Note that there is a difference between TLS 1.3     and key exporters in older versions of TLS. TLS 1.3 does     not distinguish between an empty context and no context.

  - The TLS 1.3 (draft) protocol can be enabled, by defining     NSS_ENABLE_TLS_1_3=1 when building NSS.

  - NSS includes support for the X25519 key exchange     algorithm, which is supported and enabled by default in     all versions of TLS. Notable Changes :

  - NSS can no longer be compiled with support for     additional elliptic curves. This was previously possible     by replacing certain NSS source files.

  - NSS will now detect the presence of tokens that support     additional elliptic curves and enable those curves for     use in TLS. Note that this detection has a one-off     performance cost, which can be avoided by using the     SSL_NamedGroupConfig function to limit supported groups     to those that NSS provides.

  - PKCS#11 bypass for TLS is no longer supported and has     been removed.

  - Support for 'export' grade SSL/TLS cipher suites has     been removed.

  - NSS now uses the signature schemes definition in TLS     1.3. This also affects TLS 1.2. NSS will now only     generate signatures with the combinations of hash and     signature scheme that are defined in TLS 1.3, even when     negotiating TLS 1.2.

  - This means that SHA-256 will only be used with P-256     ECDSA certificates, SHA-384 with P-384 certificates, and     SHA-512 with P-521 certificates. SHA-1 is permitted (in     TLS 1.2 only) with any certificate for backward     compatibility reasons.

  - NSS will now no longer assume that default signature     schemes are supported by a peer if there was no commonly     supported signature scheme.

  - NSS will now check if RSA-PSS signing is supported by     the token that holds the private key prior to using it     for TLS.

  - The certificate validation code contains checks to no     longer trust certificates that are issued by old WoSign     and StartCom CAs after October 21, 2016. This is     equivalent to the behavior that Mozilla will release     with Firefox 51.

  - Update to NSS 3.27.2

  - Fixed SSL_SetTrustAnchors leaks (bmo#1318561)

  - raised the minimum softokn/freebl version to 3.28 as     reported in (boo#1021636)

  - Update to NSS 3.26.2 New Functionality :

  - the selfserv test utility has been enhanced to support     ALPN (HTTP/1.1) and 0-RTT

  - added support for the System-wide crypto policy     available on Fedora Linux see     http://fedoraproject.org/wiki/Changes/CryptoPolicy

  - introduced build flag NSS_DISABLE_LIBPKIX that allows     compilation of NSS without the libpkix library Notable     Changes :

  - The following CA certificate was Added CN = ISRG Root X1

  - NPN is disabled and ALPN is enabled by default

  - the NSS test suite now completes with the experimental     TLS 1.3 code enabled

  - several test improvements and additions, including a     NIST known answer test Changes in 3.26.2

  - MD5 signature algorithms sent by the server in     CertificateRequest messages are now properly ignored.
    Previously, with rare server configurations, an MD5     signature algorithm might have been selected for client     authentication and caused the client to abort the     connection soon after.

  - Update to NSS 3.25 New functionality :

  - Implemented DHE key agreement for TLS 1.3

  - Added support for ChaCha with TLS 1.3

  - Added support for TLS 1.2 ciphersuites that use SHA384     as the PRF

  - In previous versions, when using client authentication     with TLS 1.2, NSS only supported certificate_verify     messages that used the same signature hash algorithm as     used by the PRF. This limitation has been removed.
    Notable changes :

  - An SSL socket can no longer be configured to allow both     TLS 1.3 and SSLv3

  - Regression fix: NSS no longer reports a failure if an     application attempts to disable the SSLv2 protocol.

  - The list of trusted CA certificates has been updated to     version 2.8

  - The following CA certificate was Removed Sonera Class1     CA

  - The following CA certificates were Added Hellenic     Academic and Research Institutions RootCA 2015 Hellenic     Academic and Research Institutions ECC RootCA 2015     Certplus Root CA G1 Certplus Root CA G2 OpenTrust Root     CA G1 OpenTrust Root CA G2 OpenTrust Root CA G3

  - Update to NSS 3.24 New functionality :

  - NSS softoken has been updated with the latest National     Institute of Standards and Technology (NIST) guidance     (as of 2015) :

  - Software integrity checks and POST functions are     executed on shared library load. These checks have been     disabled by default, as they can cause a performance     regression. To enable these checks, you must define     symbol NSS_FORCE_FIPS when building NSS.

  - Counter mode and Galois/Counter Mode (GCM) have checks     to prevent counter overflow.

  - Additional CSPs are zeroed in the code.

  - NSS softoken uses new guidance for how many Rabin-Miller     tests are needed to verify a prime based on prime size.

  - NSS softoken has also been updated to allow NSS to run     in FIPS Level 1 (no password). This mode is triggered by     setting the database password to the empty string. In     FIPS mode, you may move from Level 1 to Level 2 (by     setting an appropriate password), but not the reverse.

  - A SSL_ConfigServerCert function has been added for     configuring SSL/TLS server sockets with a certificate     and private key. Use this new function in place of     SSL_ConfigSecureServer,     SSL_ConfigSecureServerWithCertChain,     SSL_SetStapledOCSPResponses, and     SSL_SetSignedCertTimestamps. SSL_ConfigServerCert     automatically determines the certificate type from the     certificate and private key. The caller is no longer     required to use SSLKEAType explicitly to select a 'slot'     into which the certificate is configured (which     incorrectly identifies a key agreement type rather than     a certificate). Separate functions for configuring     Online Certificate Status Protocol (OCSP) responses or     Signed Certificate Timestamps are not needed, since     these can be added to the optional     SSLExtraServerCertData struct provided to     SSL_ConfigServerCert. Also, partial support for RSA     Probabilistic Signature Scheme (RSA-PSS) certificates     has been added. Although these certificates can be     configured, they will not be used by NSS in this     version.

  - Deprecate the member attribute authAlgorithm of type     SSLCipherSuiteInfo. Instead, applications should use the     newly added attribute authType.

  - Add a shared library (libfreeblpriv3) on Linux platforms     that define FREEBL_LOWHASH.

  - Remove most code related to SSL v2, including the     ability to actively send a SSLv2-compatible client     hello. However, the server-side implementation of the     SSL/TLS protocol still supports processing of received     v2-compatible client hello messages.

  - Disable (by default) NSS support in optimized builds for     logging SSL/TLS key material to a logfile if the     SSLKEYLOGFILE environment variable is set. To enable the     functionality in optimized builds, you must define the     symbol NSS_ALLOW_SSLKEYLOGFILE when building NSS.

  - Update NSS to protect it against the Cachebleed attack.

  - Disable support for DTLS compression.

  - Improve support for TLS 1.3. This includes support for     DTLS 1.3. Note that TLS 1.3 support is experimental and     not suitable for production use.

  - Update to NSS 3.23 New functionality :

  - ChaCha20/Poly1305 cipher and TLS cipher suites now     supported

  - Experimental-only support TLS 1.3 1-RTT mode (draft-11).
    This code is not ready for production use. Notable     changes :

  - The list of TLS extensions sent in the TLS handshake has     been reordered to increase compatibility of the Extended     Master Secret with with servers

  - The build time environment variable NSS_ENABLE_ZLIB has     been renamed to NSS_SSL_ENABLE_ZLIB

  - The build time environment variable     NSS_DISABLE_CHACHAPOLY was added, which can be used to     prevent compilation of the ChaCha20/Poly1305 code.

  - The following CA certificates were Removed

  - Staat der Nederlanden Root CA

  - NetLock Minositett Kozjegyzoi (Class QA)     Tanusitvanykiado

  - CVE-2016-2834: Memory safety bugs (boo#983639)     MFSA-2016-61 bmo#1206283 bmo#1221620 bmo#1241034     bmo#1241037

  - Update to NSS 3.22.3

  - Increase compatibility of TLS extended master secret,     don't send an empty TLS extension last in the handshake     (bmo#1243641)

  - Fixed a heap-based buffer overflow related to the     parsing of certain ASN.1 structures. An attacker could     create a specially crafted certificate which, when     parsed by NSS, would cause a crash or execution of     arbitrary code with the permissions of the user.
    (CVE-2016-1950, bmo#1245528)

  - Update to NSS 3.22.2 New functionality :

  - RSA-PSS signatures are now supported (bmo#1215295)

  - Pseudorandom functions based on hashes other than SHA-1     are now supported

  - Enforce an External Policy on NSS from a config file     (bmo#1009429)

  - CVE-2016-8635: Fix for DH small subgroup confinement     attack (bsc#1015547) Mozilla NSPR was updated to version     4.13.1: The previously released version 4.13 had changed     pipes to be nonblocking by default, and as a     consequence, PollEvent was changed to not block on     clear. The NSPR development team received reports that     these changes caused regressions in some applications     that use NSPR, and it has been decided to revert the     changes made in NSPR 4.13. NSPR 4.13.1 restores the     traditional behavior of pipes and PollEvent. Mozilla     NSPR update to version 4.13 had these changes :

  - PL_strcmp (and others) were fixed to return consistent     results when one of the arguments is NULL.

  - PollEvent was fixed to not block on clear.

  - Pipes are always nonblocking.

  - PR_GetNameForIdentity: added thread safety lock and     bound checks.

  - Removed the PLArena freelist.

  - Avoid some integer overflows.

  - fixed several comments. This update also contains     java-1_8_0-openjdk that needed to be rebuilt against the     new mozilla-nss version.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Mozilla Network Security Services (NSS) before 3.23, as used in Mozilla Firefox before 47.0, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unknown vectors. (CVE-2016-2834)

Mozilla Firefox was updated to the Firefox ESR release 45.9. Mozilla NSS was updated to support TLS 1.3 (close to release draft) and various new ciphers, PRFs, Diffie Hellman key agreement and support for more hashes. Security issues fixed in Firefox (bsc#1035082)

  - Fixed a bug in hash computation (and build with GCC 7     which complains about shifts of boolean values).
    (bsc#1030071, bmo#1348767)

  - Update to NSS 3.28.3 This is a patch release to fix     binary compatibility issues.

  - Update to NSS 3.28.1 This is a patch release to update     the list of root CA certificates.

  - The following CA certificates were Removed CN = Buypass     Class 2 CA 1 CN = Root CA Generalitat Valenciana OU =     RSA Security 2048 V3

  - The following CA certificates were Added OU = AC RAIZ     FNMT-RCM CN = Amazon Root CA 1 CN = Amazon Root CA 2 CN     = Amazon Root CA 3 CN = Amazon Root CA 4 CN = LuxTrust     Global Root 2 CN = Symantec Class 1 Public Primary     Certification Authority - G4 CN = Symantec Class 1     Public Primary Certification Authority - G6 CN =     Symantec Class 2 Public Primary Certification Authority
    - G4 CN = Symantec Class 2 Public Primary Certification     Authority - G6

  - The version number of the updated root CA list has been     set to 2.11

  - Update to NSS 3.28 New functionality :

  - NSS includes support for TLS 1.3 draft -18. This     includes a number of improvements to TLS 1.3 :

  - The signed certificate timestamp, used in certificate     transparency, is supported in TLS 1.3.

  - Key exporters for TLS 1.3 are supported. This includes     the early key exporter, which can be used if 0-RTT is     enabled. Note that there is a difference between TLS 1.3     and key exporters in older versions of TLS. TLS 1.3 does     not distinguish between an empty context and no context.

  - The TLS 1.3 (draft) protocol can be enabled, by defining     NSS_ENABLE_TLS_1_3=1 when building NSS.

  - NSS includes support for the X25519 key exchange     algorithm, which is supported and enabled by default in     all versions of TLS. Notable Changes :

  - NSS can no longer be compiled with support for     additional elliptic curves. This was previously possible     by replacing certain NSS source files.

  - NSS will now detect the presence of tokens that support     additional elliptic curves and enable those curves for     use in TLS. Note that this detection has a one-off     performance cost, which can be avoided by using the     SSL_NamedGroupConfig function to limit supported groups     to those that NSS provides.

  - PKCS#11 bypass for TLS is no longer supported and has     been removed.

  - Support for 'export' grade SSL/TLS cipher suites has     been removed.

  - NSS now uses the signature schemes definition in TLS     1.3. This also affects TLS 1.2. NSS will now only     generate signatures with the combinations of hash and     signature scheme that are defined in TLS 1.3, even when     negotiating TLS 1.2.

  - This means that SHA-256 will only be used with P-256     ECDSA certificates, SHA-384 with P-384 certificates, and     SHA-512 with P-521 certificates. SHA-1 is permitted (in     TLS 1.2 only) with any certificate for backward     compatibility reasons.

  - NSS will now no longer assume that default signature     schemes are supported by a peer if there was no commonly     supported signature scheme.

  - NSS will now check if RSA-PSS signing is supported by     the token that holds the private key prior to using it     for TLS.

  - The certificate validation code contains checks to no     longer trust certificates that are issued by old WoSign     and StartCom CAs after October 21, 2016. This is     equivalent to the behavior that Mozilla will release     with Firefox 51.

  - Update to NSS 3.27.2

  - Fixed SSL_SetTrustAnchors leaks (bmo#1318561)

  - raised the minimum softokn/freebl version to 3.28 as     reported in (boo#1021636)

  - Update to NSS 3.26.2 New Functionality :

  - the selfserv test utility has been enhanced to support     ALPN (HTTP/1.1) and 0-RTT

  - added support for the System-wide crypto policy     available on Fedora Linux see     http://fedoraproject.org/wiki/Changes/CryptoPolicy

  - introduced build flag NSS_DISABLE_LIBPKIX that allows     compilation of NSS without the libpkix library Notable     Changes :

  - The following CA certificate was Added CN = ISRG Root X1

  - NPN is disabled and ALPN is enabled by default

  - the NSS test suite now completes with the experimental     TLS 1.3 code enabled

  - several test improvements and additions, including a     NIST known answer test Changes in 3.26.2

  - MD5 signature algorithms sent by the server in     CertificateRequest messages are now properly ignored.
    Previously, with rare server configurations, an MD5     signature algorithm might have been selected for client     authentication and caused the client to abort the     connection soon after.

  - Update to NSS 3.25 New functionality :

  - Implemented DHE key agreement for TLS 1.3

  - Added support for ChaCha with TLS 1.3

  - Added support for TLS 1.2 ciphersuites that use SHA384     as the PRF

  - In previous versions, when using client authentication     with TLS 1.2, NSS only supported certificate_verify     messages that used the same signature hash algorithm as     used by the PRF. This limitation has been removed.
    Notable changes :

  - An SSL socket can no longer be configured to allow both     TLS 1.3 and SSLv3

  - Regression fix: NSS no longer reports a failure if an     application attempts to disable the SSLv2 protocol.

  - The list of trusted CA certificates has been updated to     version 2.8

  - The following CA certificate was Removed Sonera Class1     CA

  - The following CA certificates were Added Hellenic     Academic and Research Institutions RootCA 2015 Hellenic     Academic and Research Institutions ECC RootCA 2015     Certplus Root CA G1 Certplus Root CA G2 OpenTrust Root     CA G1 OpenTrust Root CA G2 OpenTrust Root CA G3

  - Update to NSS 3.24 New functionality :

  - NSS softoken has been updated with the latest National     Institute of Standards and Technology (NIST) guidance     (as of 2015) :

  - Software integrity checks and POST functions are     executed on shared library load. These checks have been     disabled by default, as they can cause a performance     regression. To enable these checks, you must define     symbol NSS_FORCE_FIPS when building NSS.

  - Counter mode and Galois/Counter Mode (GCM) have checks     to prevent counter overflow.

  - Additional CSPs are zeroed in the code.

  - NSS softoken uses new guidance for how many Rabin-Miller     tests are needed to verify a prime based on prime size.

  - NSS softoken has also been updated to allow NSS to run     in FIPS Level 1 (no password). This mode is triggered by     setting the database password to the empty string. In     FIPS mode, you may move from Level 1 to Level 2 (by     setting an appropriate password), but not the reverse.

  - A SSL_ConfigServerCert function has been added for     configuring SSL/TLS server sockets with a certificate     and private key. Use this new function in place of     SSL_ConfigSecureServer,     SSL_ConfigSecureServerWithCertChain,     SSL_SetStapledOCSPResponses, and     SSL_SetSignedCertTimestamps. SSL_ConfigServerCert     automatically determines the certificate type from the     certificate and private key. The caller is no longer     required to use SSLKEAType explicitly to select a 'slot'     into which the certificate is configured (which     incorrectly identifies a key agreement type rather than     a certificate). Separate functions for configuring     Online Certificate Status Protocol (OCSP) responses or     Signed Certificate Timestamps are not needed, since     these can be added to the optional     SSLExtraServerCertData struct provided to     SSL_ConfigServerCert. Also, partial support for RSA     Probabilistic Signature Scheme (RSA-PSS) certificates     has been added. Although these certificates can be     configured, they will not be used by NSS in this     version.

  - Deprecate the member attribute authAlgorithm of type     SSLCipherSuiteInfo. Instead, applications should use the     newly added attribute authType.

  - Add a shared library (libfreeblpriv3) on Linux platforms     that define FREEBL_LOWHASH.

  - Remove most code related to SSL v2, including the     ability to actively send a SSLv2-compatible client     hello. However, the server-side implementation of the     SSL/TLS protocol still supports processing of received     v2-compatible client hello messages.

  - Disable (by default) NSS support in optimized builds for     logging SSL/TLS key material to a logfile if the     SSLKEYLOGFILE environment variable is set. To enable the     functionality in optimized builds, you must define the     symbol NSS_ALLOW_SSLKEYLOGFILE when building NSS.

  - Update NSS to protect it against the Cachebleed attack.

  - Disable support for DTLS compression.

  - Improve support for TLS 1.3. This includes support for     DTLS 1.3. Note that TLS 1.3 support is experimental and     not suitable for production use.

  - Update to NSS 3.23 New functionality :

  - ChaCha20/Poly1305 cipher and TLS cipher suites now     supported

  - Experimental-only support TLS 1.3 1-RTT mode (draft-11).
    This code is not ready for production use. Notable     changes :

  - The list of TLS extensions sent in the TLS handshake has     been reordered to increase compatibility of the Extended     Master Secret with with servers

  - The build time environment variable NSS_ENABLE_ZLIB has     been renamed to NSS_SSL_ENABLE_ZLIB

  - The build time environment variable     NSS_DISABLE_CHACHAPOLY was added, which can be used to     prevent compilation of the ChaCha20/Poly1305 code.

  - CVE-2016-8635: Fix for DH small subgroup confinement     attack (bsc#1015547) Mozilla NSPR was updated to version     4.13.1: The previously released version 4.13 had changed     pipes to be nonblocking by default, and as a     consequence, PollEvent was changed to not block on     clear. The NSPR development team received reports that     these changes caused regressions in some applications     that use NSPR, and it has been decided to revert the     changes made in NSPR 4.13. NSPR 4.13.1 restores the     traditional behavior of pipes and PollEvent. Mozilla     NSPR update to version 4.13 had these changes :

  - PL_strcmp (and others) were fixed to return consistent     results when one of the arguments is NULL.

  - PollEvent was fixed to not block on clear.

  - Pipes are always nonblocking.

  - PR_GetNameForIdentity: added thread safety lock and     bound checks.

  - Removed the PLArena freelist.

  - Avoid some integer overflows.

  - fixed several comments.

Several vulnerabilities were discovered in NSS, the cryptography library developed by the Mozilla project.

  - CVE-2015-4000     David Adrian et al. reported that it may be feasible to     attack Diffie-Hellman-based cipher suites in certain     circumstances, compromising the confidentiality and     integrity of data encrypted with Transport Layer     Security (TLS).

  - CVE-2015-7181 CVE-2015-7182 CVE-2016-1950     Tyson Smith, David Keeler, and Francis Gabriel     discovered heap-based buffer overflows in the ASN.1 DER     parser, potentially leading to arbitrary code execution.

  - CVE-2015-7575     Karthikeyan Bhargavan discovered that TLS client     implementation accepted MD5-based signatures for TLS 1.2     connections with forward secrecy, weakening the intended     security strength of TLS connections.

  - CVE-2016-1938     Hanno Boeck discovered that NSS miscomputed the result     of integer division for certain inputs. This could     weaken the cryptographic protections provided by NSS.
    However, NSS implements RSA-CRT leak hardening, so RSA     private keys are not directly disclosed by this issue.

  - CVE-2016-1978     Eric Rescorla discovered a use-after-free vulnerability     in the implementation of ECDH-based TLS handshakes, with     unknown consequences.

  - CVE-2016-1979     Tim Taubert discovered a use-after-free vulnerability in     ASN.1 DER processing, with application-specific impact.

  - CVE-2016-2834     Tyson Smith and Jed Davis discovered unspecified     memory-safety bugs in NSS.

In addition, the NSS library did not ignore environment variables in processes which underwent a SUID/SGID/AT_SECURE transition at process start. In certain system configurations, this allowed local users to escalate their privileges.

This update contains further correctness and stability fixes without immediate security impact.

Versions of Mozilla Firefox earlier than 47.0 are unpatched for the following vulnerabilities :

 - Multiple memory corruption issues exist that allow an unauthenticated, remote attacker to execute arbitrary code. (CVE-2016-2815, CVE-2016-2818)
 - An overflow condition exists that is triggered when handling HTML5 fragments in foreign contexts (e.g., under <svg> nodes).  An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in the execution of arbitrary code. (CVE-2016-2819)
 - A use-after-free error exists that is triggered when deleting DOM table elements in 'contenteditable' mode.  An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-2821)
 - A spoofing vulnerability exists due to improper handling of SELECT elements.  An unauthenticated, remote attacker can exploit this to spoof the contents of the address bar. (CVE-2016-2822)
 - A same-origin bypass vulnerability exists that is triggered when handling 'location.host' property values set after the creation of invalid 'data:' URIs.  An unauthenticated, remote attacker can exploit this to partially bypass same-origin policy protections. (CVE-2016-2825)
 - A use-after-free error exists that is triggered when destroying the recycle pool of a texture used during the processing of WebGL content.  An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-2828)
 - A flaw exists in 'browser/modules/webrtcUI.jsm' that is triggered when handling a large number of permission requests over a small period of time.  An unauthenticated, remote attacker can exploit this to cause the incorrect icon to be displayed in a given permission request, potentially resulting in a user approving unintended permission requests. (CVE-2016-2829)
 - A flaw exists that is triggered when handling paired fullscreen and pointerlock requests in combination with closing windows.  An unauthenticated, remote attacker can exploit this to create an unauthorized pointerlock, resulting in a denial of service condition.  Additionally, an attacker can exploit this to conduct spoofing and clickjacking attacks. (CVE-2016-2831)
 - An information disclosure vulnerability exists that is triggered when handling CSS pseudo-classes.  An unauthenticated, remote attacker can exploit this disclose a list of installed plugins. (CVE-2016-2832)
 - A Content Security Policy (CSP) bypass exists that is triggered when handling specially crafted cross-domain Java applets.  An unauthenticated, remote attacker can exploit this to bypass the CSP and conduct cross-site scripting attacks. (CVE-2016-2833)
 - Multiple unspecified flaws exist in the Mozilla Network Security Services (NSS) component that allow an attacker to have an unspecified impact. (CVE-2016-2834)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2993-1 advisory.

    Christian Holler, Gary Kwong, Jesse Ruderman, Tyson Smith, Timothy Nikkel, Sylvestre Ledru, Julian Seward,     Olli Pettay, Karl Tomlinson, Christoph Diehl, Julian Hector, Jan de Mooij, Mats Palmgren, and Tooru     Fujisawa discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a     specially crafted website, an attacker could potentially exploit these to cause a denial of service via     application crash, or execute arbitrary code. (CVE-2016-2815, CVE-2016-2818)

    A buffer overflow was discovered when parsing HTML5 fragments in some circumstances. If a user were     tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a     denial of service via application crash, or execute arbitrary code. (CVE-2016-2819)

    A use-after-free was discovered in contenteditable mode in some circumstances. If a user were tricked in     to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of     service via application crash, or execute arbitrary code. (CVE-2016-2821)

    Jordi Chancel discovered a way to use a persistent menu within a <select> element and place this in an     arbitrary location. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to spoof the addressbar contents. (CVE-2016-2822)

    Armin Razmdjou that the location.host property can be set to an arbitrary string after creating an invalid     data: URI. If a user were tricked in to opening a specially crafted website, an attacker could potentially     exploit this to bypass some same-origin protections. (CVE-2016-2825)

    A use-after-free was discovered when processing WebGL content in some circumstances. If a user were     tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a     denial of service via application crash, or execute arbitrary code. (CVE-2016-2828)

    Tim McCormack discovered that the permissions notification can show the wrong icon when a page requests     several permissions in quick succession. An attacker could potentially exploit this by tricking the user     in to giving consent for access to the wrong resource. (CVE-2016-2829)

    It was discovered that a pointerlock can be created in a fullscreen window without user consent in some     circumstances, and this pointerlock cannot be cancelled without quitting Firefox. If a user were tricked     in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of     service or conduct clickjacking attacks. (CVE-2016-2831)

    John Schoenick discovered that CSS pseudo-classes can leak information about plugins that are installed     but disabled. An attacker could potentially exploit this to fingerprint users. (CVE-2016-2832)

    Matt Wobensmith discovered that Content Security Policy (CSP) does not block the loading of cross-domain     Java applets when specified by policy. An attacker could potentially exploit this to bypass CSP     protections and conduct cross-site scripting (XSS) attacks. (CVE-2016-2833)

    In addition, multiple unspecified security issues were discovered in NSS. (CVE-2016-2834)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote Windows host is prior to 47. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code. (CVE-2016-2815, CVE-2016-2818)

  - An overflow condition exists that is triggered when     handling HTML5 fragments in foreign contexts (e.g.,     under <svg> nodes). An unauthenticated, remote attacker     can exploit this to cause a heap-based buffer overflow,     resulting in the execution of arbitrary code.
    (CVE-2016-2819)

  - A use-after-free error exists that is triggered when     deleting DOM table elements in 'contenteditable' mode.
    An unauthenticated, remote attacker can exploit this to     dereference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-2821)

  - A spoofing vulnerability exists due to improper handling     of SELECT elements. An unauthenticated, remote attacker     can exploit this to spoof the contents of the address     bar. (CVE-2016-2822)

  - An out-of-bounds write error exists in the ANGLE     graphics library due to improper size checking while     writing to an array during WebGL shader operations. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2016-2824)

  - A same-origin bypass vulnerability exists that is     triggered when handling location.host property values     set after the creation of invalid 'data:' URIs. An     unauthenticated, remote attacker can exploit this to     partially bypass same-origin policy protections.
    (CVE-2016-2825)

  - A privilege escalation vulnerability exists in the     Windows updater utility due to improper extraction of     files from MAR archives. A local attacker can exploit     this to replace the extracted files, allowing the     attacker to gain elevated privileges. (CVE-2016-2826)

  - A use-after-free error exists that is triggered when     destroying the recycle pool of a texture used during the     processing of WebGL content. An unauthenticated, remote     attacker can exploit this to dereference already freed     memory, resulting in the execution of arbitrary code.
    (CVE-2016-2828)

  - A flaw exists in browser/modules/webrtcUI.jsm that is     triggered when handling a large number of permission     requests over a small period of time. An     unauthenticated, remote attacker can exploit this to     cause the incorrect icon to be displayed in a given     permission request, potentially resulting in a user     approving unintended permission requests.
    (CVE-2016-2829)

  - A flaw exists that is triggered when handling paired     fullscreen and pointerlock requests in combination with     closing windows. An unauthenticated, remote attacker can     exploit this to create an unauthorized pointerlock,     resulting in a denial of service condition.
    Additionally, an attacker can exploit this to conduct     spoofing and clickjacking attacks. (CVE-2016-2831)

  - An information disclosure vulnerability exists that is     triggered when handling CSS pseudo-classes. An     unauthenticated, remote attacker can exploit this     disclose a list of installed plugins. (CVE-2016-2832)

  - A Content Security Policy (CSP) bypass exists that is     triggered when handling specially crafted cross-domain     Java applets. An unauthenticated, remote attacker can     exploit this to bypass the CSP and conduct cross-site     scripting attacks. (CVE-2016-2833)

  - Multiple unspecified flaws exist in the Mozilla Network     Security Services (NSS) component that allow an attacker     to have an unspecified impact. (CVE-2016-2834)

The version of Firefox installed on the remote Mac OS X host is prior to 47. It is, therefore, affected by multiple vulnerabilities :

An     unauthenticated, remote attacker can exploit this to     cause the incorrect icon to be displayed in a given     permission request, potentially resulting in a user     approving unintended permission requests.
    (CVE-2016-2829)

  - A flaw exists that is triggered when handling paired     fullscreen and pointerlock requests in combination with     closing windows. An unauthenticated, remote attacker can     exploit this to create an unauthorized pointerlock,     resulting in a denial of service condition.
    Additionally, an attacker can exploit this to conduct     spoofing and clickjacking attacks. (CVE-2016-2831)

  - An information disclosure vulnerability exists that is     triggered when handling CSS pseudo-classes. An     unauthenticated, remote attacker can exploit this     disclose a list of installed plugins. (CVE-2016-2832)

  - A Content Security Policy (CSP) bypass exists that is     triggered when handling specially crafted cross-domain     Java applets. An unauthenticated, remote attacker can     exploit this to bypass the CSP and conduct cross-site     scripting attacks. (CVE-2016-2833)

  - Multiple unspecified flaws exist in the Mozilla Network     Security Services (NSS) component that allow an attacker     to have an unspecified impact. (CVE-2016-2834)
