Description

Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
applications. Netscape Portable Runtime (NSPR) provides platform
independence for non-GUI operating system facilities.

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 this issue.
