Security Fixes in NSS 3.19.2.3
- Bug 1245528 / CVE-2016-1950 - Fixed a heap-based buffer overflow related to the parsing of certain ASN.1 structures. An attacker could create a specially-crafted certificate which, when parsed by NSS, would cause a crash or execution of arbitrary code with the permissions of the user.

The NSS development team would like to thank security researcher Francis Gabriel for responsibly disclosing the issue in Bug 1245528.
Compatibility
NSS 3.19.2.3 shared libraries are backward compatible with all older NSS 3.x shared libraries. A program linked with older NSS 3.x shared libraries will work with NSS 3.19.2.3 shared libraries without recompiling or relinking. Furthermore, applications that restrict their use of NSS APIs to the functions listed in NSS Public Functions will remain compatible with future versions of the NSS shared libraries.
