The Add-on SDK in Mozilla Firefox before 42.0 misinterprets a "script: false" panel setting, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via inline JavaScript code that is executed within a third-party extension.

The remote host is affected by the vulnerability described in GLSA-201512-10 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox and       Mozilla Thunderbird. Please review the CVE identifiers referenced below       for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The version of Mozilla Firefox is prior to 42.0 and is affected by multiple vulnerabilities : 

 - Multiple flaws in the browser engine allow remote attackers to corrupt memory and potentially execute arbitrary code. (CVE-2015-4513, CVE-2015-4514)
 - A flaw exists that is triggered when handling type 3 messages as part of the NTLM authentication exchange. This may allow an attacker to disclose system hostname and windows domain information. (CVE-2015-4515)
 - A flaw exists related to the whitelist used by Reader View to disable script for rendered pages being too permissive. This may allow an attacker to bypass CSP protections and in turn potentially conduct XSS attacks. (CVE-2015-4518)
 - An unspecified use-after-poison flaw exists in Mozilla Network Security Services (NSS) in the 'sec_asn1d_parse_leaf()' function that may allow an attacker to execute arbitrary code. (CVE-2015-7181)
 - An overflow condition exists in Mozilla Network Security Services (NSS) in the ASN.1 decoder. The issue is triggered as user-supplied input is not properly validated when handling an OCTET STRING. This may allow an attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2015-7182)
 - An integer overflow condition exists in Netscape Portable Runtime (NSPR) in the PL_ARENA_ALLOCATE macro that is triggered as user-supplied input is not properly validated during memory allocation. This may allow an attacker to corrupt memory, crashing an application linked against the library or potentially allowing the execution of arbitrary code. (CVE-2015-7183)
 - A flaw exists in the 'fetch()' API that is due it failing to properly implement the Cross-Origin Resource Sharing (CORS) feature. This may allow an attacker to potentially gain unauthorized access to cross-origin information. (CVE-2015-7184)- A flaw exists that is due to the program failing to enforce settings when disabling scripts in the Add-on SDK panel. By defining a panel with "script: false", all script execution is designed to be disabled. With a crafted web site, an attacker may be able to bypass this restriction, facilitating scripting attacks. (CVE-2015-7187)
 - A flaw exists in 'netwerk/base/nsStandardURL.cpp' that is triggered during the handling of trailing whitespaces in the IP address hostname. This may allow an attacker to bypass the same-origin policy. (CVE-2015-7188)
 - A race condition exists in the 'JPEGEncoder()' function. The issue is triggered as user-supplied input is not properly validated when handling canvas elements. This may allow an attacker to cause a heap-based buffer overflow and potentially execute arbitrary code. (CVE-2015-7189)
 - A flaw exists (Firefox for OS X only) in the 'ConvertToNSArray()' function in 'accessible/mac/mozAccessible.mm.' The issue is triggered when an accessibility tool requests the index of a table row via the 'NSAccessibilityIndexAttribute' value. This may allow an attacker to potentially execute arbitrary code. (CVE-2015-7192)
 - A flaw exists that is triggered during the handling of content-type headers for multiple media types returned from a server. This may allow an attacker to bypass cross-origin resource sharing (CORS) and perform simple request instead of a 'preflight' request. (CVE-2015-7193)
 - A flaw exists in the 'nsZipArchive::GetData()' function in 'modules/libjar/nsZipArchive.cpp' that is triggered as user-supplied input is not properly validated when handling ZIP archives. This may allow an attacker to corrupt memory and potentially execute arbitrary code. (CVE-2015-7194)
 - A flaw exists that is triggered during the parsing of escaped characters in the hostname of location headers. This may allow an attacker to gain access to arbitrary site-specific token information. (CVE-2015-7195)
 - A flaw exists in the '_releaseobject()' function in 'dom/plugins/base/nsNPAPIPlugin.cpp' that is triggered when JavaScript wrappers become deallocated during use. This may allow an attacker to corrupt memory and potentially execute arbitrary code. (CVE-2015-7196)
 - A flaw exists in the 'WebSocketImpl::Init()' function in 'dom/base/WebSocket.cpp' that is triggered when determining the origin of the entry settings object for workers. This may allow an attacker to bypass the mixed content WebSocket policy. (CVE-2015-7197)
 - An overflow condition exists in the 'WebGLTexture::EnsureInitializedImageData()' function in 'dom/canvas/WebGLTexture.cpp.' The issue is triggered as user-supplied input is not properly validated. This may allow an attacker to cause a buffer overflow and potentially execute arbitrary code. (CVE-2015-7198)
 - A flaw exists in 'dom/svg/SVGPathSegListSMILType.cpp' related to missing return value checks for the 'AddWeightedPathSegLists()' function during SVG rendering. This may allow an attacker to corrupt memory and execute arbitrary code. (CVE-2015-7199)
 - A flaw exists that is due to missing status checks in CryptoKey related to OOM (Out-of-Memory) conditions. This may allow an attacker to make changes to crpytographic keys and potentially execute arbitrary code. (CVE-2015-7200)

  - Install the static libfreebl.a that is needed in order     to link Sun elliptical curves provider in Java 7.

This includes the update of Mozilla NSS to NSS 3.20 New functionality :

  - The TLS library has been extended to support DHE     ciphersuites in server applications. New Functions :

  - SSL_DHEGroupPrefSet - Configure the set of     allowed/enabled DHE group parameters that can be used by     NSS for a server socket.

  - SSL_EnableWeakDHEPrimeGroup - Enable the use of weak DHE     group parameters that are smaller than the library     default's minimum size. New Types :

  - SSLDHEGroupType - Enumerates the set of DHE parameters     embedded in NSS that can be used with function     SSL_DHEGroupPrefSet. New Macros :

  - SSL_ENABLE_SERVER_DHE - A socket option user to enable     or disable DHE ciphersuites for a server socket. Notable     Changes :

  - For backwards compatibility reasons, the server side     implementation of the TLS library keeps all DHE     ciphersuites disabled by default. They can be enabled     with the new socket option SSL_ENABLE_SERVER_DHE and the     SSL_OptionSet or the SSL_OptionSetDefault API.

  - The server side implementation of the TLS implementation     does not support session tickets when using a DHE     ciphersuite (see bmo#1174677).

  - Support for the following ciphersuites has been added :

  - TLS_DHE_DSS_WITH_AES_128_GCM_SHA256

  - TLS_DHE_DSS_WITH_AES_128_CBC_SHA256

  - TLS_DHE_DSS_WITH_AES_256_CBC_SHA256

  - By default, the server side TLS implementation will use     DHE parameters with a size of 2048 bits when using DHE     ciphersuites.

  - NSS embeds fixed DHE parameters sized 2048, 3072, 4096,     6144 and 8192 bits, which were copied from version 08 of     the Internet-Draft 'Negotiated Finite Field     Diffie-Hellman Ephemeral Parameters for TLS', Appendix     A.

  - A new API SSL_DHEGroupPrefSet has been added to NSS,     which allows a server application to select one or     multiple of the embedded DHE parameters as the preferred     parameters. The current implementation of NSS will     always use the first entry in the array that is passed     as a parameter to the SSL_DHEGroupPrefSet API. In future     versions of the TLS implementation, a TLS client might     signal a preference for certain DHE parameters, and the     NSS TLS server side implementation might select a     matching entry from the set of parameters that have been     configured as preferred on the server side.

  - NSS optionally supports the use of weak DHE parameters     with DHE ciphersuites to support legacy clients. In     order to enable this support, the new API     SSL_EnableWeakDHEPrimeGroup must be used. Each time this     API is called for the first time in a process, a fresh     set of weak DHE parameters will be randomly created,     which may take a long amount of time. Please refer to     the comments in the header file that declares the     SSL_EnableWeakDHEPrimeGroup API for additional details.

  - The size of the default PQG parameters used by certutil     when creating DSA keys has been increased to use 2048     bit parameters.

  - The selfserv utility has been enhanced to support the     new DHE features.

  - NSS no longer supports C compilers that predate the ANSI     C standard (C89).

It also includes the update to NSS 3.19.3; certstore updates only

  - A flaw exists in the CryptoKey interface implementation     due to missing status checks. A remote attacker can     exploit this to make changes to cryptographic keys and     execute arbitrary code. (CVE-2015-7200)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2785-1 advisory.

    Christian Holler, David Major, Jesse Ruderman, Tyson Smith, Boris Zbarsky, Randell Jesup, Olli Pettay,     Karl Tomlinson, Jeff Walden, Gary Kwong, Andrew McCreight, Georg Fritzsche, and Carsten Book 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 with the privileges of the user invoking Firefox. (CVE-2015-4513, CVE-2015-4514)

    Tim Brown discovered that Firefox discloses the hostname during NTLM authentication in some circumstances.
    If a user were tricked in to opening a specially crafted website with NTLM v1 enabled, an attacker could     exploit this to obtain sensitive information. (CVE-2015-4515)

    Mario Heiderich and Frederik Braun discovered that CSP could be bypassed in reader mode in some     circumstances. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2015-4518)

    Tyson Smith and David Keeler discovered a use-after-poison and buffer overflow in NSS. 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 with the privileges of the user     invoking Firefox. (CVE-2015-7181, CVE-2015-7182)

    Ryan Sleevi discovered an integer overflow in NSPR. 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 with the privileges of the user invoking Firefox. (CVE-2015-7183)

    Jason Hamilton, Peter Arremann and Sylvain Giroux discovered that panels created via the Addon SDK with {     script: false } could still execute inline script. If a user installed an addon that relied on this as a     security mechanism, an attacker could potentially exploit this to conduct cross-site scripting (XSS)     attacks, depending on the source of the panel content. (CVE-2015-7187)

    Micha Bentkowski discovered that adding white-space to hostnames that are IP address can bypass same-     origin protections. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2015-7188)

    Looben Yang discovered a buffer overflow during script interactions with the canvas element 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     with the privileges of the user invoking Firefox. (CVE-2015-7189)

    Shinto K Anto discovered that CORS preflight is bypassed when receiving non-standard Content-Type headers     in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could     potentially exploit this to bypass same-origin restrictions. (CVE-2015-7193)

    Gustavo Grieco discovered a buffer overflow in libjar 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 with the privileges of the user invoking Firefox.
    (CVE-2015-7194)

    Frans Rosn discovered that certain escaped characters in the Location header are parsed incorrectly,     resulting in a navigation to the previously parsed version of a URL. If a user were tricked in to opening     a specially crafted website, an attacker could potentially exploit this to obtain site specific tokens.
    (CVE-2015-7195)

    Vytautas Staraitis discovered a garbage collection crash when interacting with Java applets in some     circumstances. If a user were tricked in to opening a specially crafted website with the Java plugin     installed, an attacker could potentially exploit this to execute arbitrary code with the privileges of the     user invoking Firefox. (CVE-2015-7196)

    Ehsan Akhgari discovered a mechanism for a web worker to bypass secure requirements for web sockets. If a     user were tricked in to opening a specially crafted website, an attacker could exploit this to bypass the     mixed content web socket policy. (CVE-2015-7197)

    Ronald Crane discovered several vulnerabilities through code-inspection. 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 with the privileges of the user invoking Firefox.
