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)
