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 race condition was found in the way NSS verified certain certificates.
A remote attacker could use this flaw to crash an application using NSS or,
possibly, execute arbitrary code with the privileges of the user running
that application. (CVE-2014-1544)

Red Hat would like to thank the Mozilla project for reporting
CVE-2014-1544. Upstream acknowledges Tyson Smith and Jesse Schwartzentruber
as the original reporters.

Users of NSS are advised to upgrade to these updated packages, which
correct this issue. After installing this update, applications using NSS
must be restarted for this update to take effect.

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
