"Updated nss and nspr packages that fix three security issues are now
available for Red Hat Enterprise Linux 5.

Red Hat Product Security has rated this update as having Critical
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 cross-platform development of security-enabled client and
server applications. Netscape Portable Runtime (NSPR) provides
platform independence for non-GUI operating system facilities.

A use-after-poison flaw and a heap-based buffer overflow flaw were
found in the way NSS parsed certain ASN.1 structures. An attacker
could use these flaws to cause NSS to crash or execute arbitrary code
with the permissions of the user running an application compiled
against the NSS library. (CVE-2015-7181, CVE-2015-7182)

A heap-based buffer overflow was found in NSPR. An attacker could use
this flaw to cause NSPR to crash or execute arbitrary code with the
permissions of the user running an application compiled against the
NSPR library. (CVE-2015-7183)

Red Hat would like to thank the Mozilla project for reporting these
issues. Upstream acknowledges Tyson Smith, David Keeler and Ryan
Sleevi as the original reporter.

All nss and nspr users are advised to upgrade to these updated
packages, which contain backported patches to correct these issues."
