Description

Network Security Services (NSS) is a set of libraries designed to supportthe cross-platform development of security-enabled client and serverapplications. The nss-util package provides a set of utilities for NSS andthe Softoken module.A heap-based buffer overflow flaw was found in the way NSS parsed certainASN.1 structures. An attacker could use this flaw to create a speciallycrafted certificate which, when parsed by NSS, could cause it to crash, orexecute arbitrary code, using the permissions of the user running anapplication 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, whichcontain a backported patch to correct this issue. For the update to takeeffect, all applications linked to the nss and nss-util libraries must berestarted, or the system rebooted.
