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. The nss-util package provides a set of utilities for NSS and
the Softoken module.
A heap-based buffer overflow flaw was found in the way NSS parsed certain
ASN.1 structures. 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-2016-1950)
Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges Francis Gabriel as the original reporter.
All nss-util users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For the update to take
effect, all applications linked to the nss and nss-util libraries must be
restarted, or the system rebooted.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
