The ssl_Do1stHandshake function in sslsecur.c in libssl in Mozilla Network Security Services (NSS) before 3.15.4, when the TLS False Start feature is enabled, allows man-in-the-middle attackers to spoof SSL servers by using an arbitrary X.509 certificate during certain handshake traffic.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has nss packages installed that are affected by multiple vulnerabilities:

  - A flaw was found in the way NSS responded to an     SSLv2-compatible ClientHello with a ServerHello that had     an all-zero random. A man-in-the-middle attacker could     use this flaw in a passive replay attack.
    (CVE-2018-12384)

  - The TLS implementation in Mozilla Network Security     Services (NSS) does not properly consider timing side-     channel attacks on a noncompliant MAC check operation     during the processing of malformed CBC padding, which     allows remote attackers to conduct distinguishing     attacks and plaintext-recovery attacks via statistical     analysis of timing data for crafted packets, a related     issue to CVE-2013-0169. (CVE-2013-1620)

  - Mozilla Network Security Services (NSS) before 3.15.2     does not ensure that data structures are initialized     before read operations, which allows remote attackers to     cause a denial of service or possibly have unspecified     other impact via vectors that trigger a decryption     failure. (CVE-2013-1739)

  - A flaw was found in the way TLS False Start was     implemented in NSS. An attacker could use this flaw to     potentially return unencrypted information from the     server. (CVE-2013-1740)

  - Integer overflow in Mozilla Network Security Services     (NSS) 3.15 before 3.15.3 allows remote attackers to     cause a denial of service or possibly have unspecified     other impact via a large size value. (CVE-2013-1741)

  - Mozilla Network Security Services (NSS) 3.14 before     3.14.5 and 3.15 before 3.15.3 allows remote attackers to     cause a denial of service or possibly have unspecified     other impact via invalid handshake packets.
    (CVE-2013-5605)

  - The CERT_VerifyCert function in lib/certhigh/certvfy.c     in Mozilla Network Security Services (NSS) 3.15 before     3.15.3 provides an unexpected return value for an     incompatible key-usage certificate when the     CERTVerifyLog argument is valid, which might allow     remote attackers to bypass intended access restrictions     via a crafted certificate. (CVE-2013-5606)

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

CVE-2013-1740 The ssl_Do1stHandshake function in sslsecur.c in libssl in Mozilla Network Security Services (NSS) before 3.15.4, when the TLS False Start feature is enabled, allows man-in-the-middle attackers to spoof SSL servers by using an arbitrary X.509 certificate during certain handshake traffic.

CVE-2014-1490 Race condition in libssl in Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via vectors involving a resumption handshake that triggers incorrect replacement of a session ticket.

CVE-2014-1491 Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, does not properly restrict public values in Diffie-Hellman key exchanges, which makes it easier for remote attackers to bypass cryptographic protection mechanisms in ticket handling by leveraging use of a certain value.

CVE-2014-1492 The cert_TestHostName function in lib/certdb/certdb.c in the certificate-checking implementation in Mozilla Network Security Services (NSS) before 3.16 accepts a wildcard character that is iframeded in an internationalized domain name's U-label, which might allow man-in-the-middle attackers to spoof SSL servers via a crafted certificate.

CVE-2014-1544 Use-after-free vulnerability in the CERT_DestroyCertificate function in libnss3.so in Mozilla Network Security Services (NSS) 3.x, as used in Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7, allows remote attackers to execute arbitrary code via vectors that trigger certain improper removal of an NSSCertificate structure from a trust domain.

CVE-2014-1545 Mozilla Netscape Portable Runtime (NSPR) before 4.10.6 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write) via vectors involving the sprintf and console functions.

The Oracle OpenSSO agent installed on the remote host is missing a vendor-supplied update. It is, therefore, affected by multiple vulnerabilities in the bundled Mozilla Network Security Services, the most serious of which can allow remote code execution.

The remote host has a version of Oracle WebLogic Server installed that is affected by multiple unspecified vulnerabilities affecting the following components :

  - WebLogic Tuxedo Connector
  - WLS-Console (Struts based)
  - WLS-Console

Updated nss and nspr packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.

A flaw was found in the way TLS False Start was implemented in NSS. An attacker could use this flaw to potentially return unencrypted information from the server. (CVE-2013-1740)

A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application.
(CVE-2014-1490)

It was found that NSS accepted weak Diffie-Hellman Key exchange (DHKE) parameters. This could possibly lead to weak encryption being used in communication between the client and the server. (CVE-2014-1491)

An out-of-bounds write flaw was found in NSPR. A remote attacker could potentially use this flaw to crash an application using NSPR or, possibly, execute arbitrary code with the privileges of the user running that application. This NSPR flaw was not exposed to web content in any shipped version of Firefox. (CVE-2014-1545)

It was found that the implementation of Internationalizing Domain Names in Applications (IDNA) hostname matching in NSS did not follow the RFC 6125 recommendations. This could lead to certain invalid certificates with international characters to be accepted as valid.
(CVE-2014-1492)

Red Hat would like to thank the Mozilla project for reporting the CVE-2014-1490, CVE-2014-1491, and CVE-2014-1545 issues. Upstream acknowledges Brian Smith as the original reporter of CVE-2014-1490, Antoine Delignat-Lavaud and Karthikeyan Bhargavan as the original reporters of CVE-2014-1491, and Abhishek Arya as the original reporter of CVE-2014-1545.

The nss and nspr packages have been upgraded to upstream version 3.16.1 and 4.10.6 respectively, which provide a number of bug fixes and enhancements over the previous versions. (BZ#1110857, BZ#1110860)

This update also fixes the following bugs :

* Previously, when the output.log file was not present on the system, the shell in the Network Security Services (NSS) specification handled test failures incorrectly as false positive test results.
Consequently, certain utilities, such as 'grep', could not handle failures properly. This update improves error detection in the specification file, and 'grep' and other utilities now handle missing files or crashes as intended. (BZ#1035281)

* Prior to this update, a subordinate Certificate Authority (CA) of the ANSSI agency incorrectly issued an intermediate certificate installed on a network monitoring device. As a consequence, the monitoring device was enabled to act as an MITM (Man in the Middle) proxy performing traffic management of domain names or IP addresses that the certificate holder did not own or control. The trust in the intermediate certificate to issue the certificate for an MITM device has been revoked, and such a device can no longer be used for MITM attacks. (BZ#1042684)

* Due to a regression, MD5 certificates were rejected by default because Network Security Services (NSS) did not trust MD5 certificates. With this update, MD5 certificates are supported in Red Hat Enterprise Linux 5. (BZ#11015864)

Users of nss and nspr are advised to upgrade to these updated packages, which correct these issues and add these enhancements.

Mozilla NSS was updated to 3.15.4 :

  - required for Firefox 27

  - regular CA root store update (1.96)

  - Reordered the cipher suites offered in SSL/TLS client     hello messages to match modern best practices.

  - Improved SSL/TLS false start. In addition to enabling     the SSL_ENABLE_FALSE_START option, an application must     now register a callback using the     SSL_SetCanFalseStartCallback function.

  - When false start is enabled, libssl will sometimes     return unencrypted, unauthenticated data from PR_Recv     (CVE-2013-1740, bmo#919877)

  - MFSA 2014-12/CVE-2014-1490/CVE-2014-1491 NSS ticket     handling issues New functionality

  - Implemented OCSP querying using the HTTP GET method,     which is the new default, and will fall back to the HTTP     POST method.

  - Implemented OCSP server functionality for testing     purposes (httpserv utility).

  - Support SHA-1 signatures with TLS 1.2 client     authentication.

  - Added the --empty-password command-line option to     certutil, to be used with -N: use an empty password when     creating a new database.

  - Added the -w command-line option to pp: don't wrap long     output lines.

Update of the nss, nss-softokn, and nss-util packages to nss-3.15.4, a patch release for NSS 3.15 which includes the following security-relevant bug :

(CVE-2013-1740) When false start is enabled, libssl will sometimes return unencrypted, unauthenticated data from PR_Recv

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

New mozilla-nss packages are available for Slackware 14.0, 14.1, and
-current to fix a security issue.

Brian Smith discovered that NSS incorrectly handled the TLS False Start feature. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to spoof SSL servers.

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

A vulnerability has been discovered and corrected in Mozilla NSS :

The ssl_Do1stHandshake function in sslsecur.c in libssl in Mozilla Network Security Services (NSS) before 3.15.4, when the TLS False Start feature is enabled, allows man-in-the-middle attackers to spoof SSL servers by using an arbitrary X.509 certificate during certain handshake traffic (CVE-2013-1740).

The updated packages have been upgraded to the 3.15.4 version which is not vulnerable to this issue.
