Red Hat: 2013:1840-01 Important: NSS Remote Code Execution Threat

red hat
Calendar Grey December 16, 2013
Dist Redhat Esm H88
Major NSS announcement from Red Hat tackles vulnerabilities in Linux distributions, promoting enhanced security measures.
Updated nss packages that fix one security issue are now available for Red Hat Enterprise Linux 6.2, 6.3, and 6.4 Extended Update Support

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/site/articles/11258

Summary

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 NSS handled invalid handshake packets. A remote attacker could use this flaw to cause a TLS/SSL client using NSS to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2013-5605)
All NSS users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, applications using NSS must be restarted for the changes to take effect.
