    1. Summary:
    
    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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
    Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
    Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, x86_64
    
    3. Description:
    
    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.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    https://access.redhat.com/articles/11258
