CentOS Errata and Security Advisory CESA-2015:1980
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)
