Type/Severity

Security Advisory: Critical

Topic

An update for nss is now available for Red Hat Enterprise Linux 5.9 Long Life.

Description

Network Security Services (NSS) is a set of libraries designed to support the
cross-platform development of security-enabled client and server applications.

Security Fix(es):

• An out-of-bounds write flaw was found in the way NSS performed certain
  Base64-decoding operations. An attacker could use this flaw to create a
  specially crafted certificate which, when parsed by NSS, could cause it to crash
  or execute arbitrary code, using the permissions of the user running an
  application compiled against the NSS library. (CVE-2017-5461)
  

Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges Ronald Crane as the original reporter.
