Summary

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.
A flaw was found in the way the ASN.1 (Abstract Syntax Notation One) decoder in NSS handled zero length items. This flaw could cause the decoder to incorrectly skip or replace certain items with a default value, or could cause an application to crash if, for example, it received a specially-crafted OCSP (Online Certificate Status Protocol) response. (CVE-2012-0441)
The nspr package has been upgraded to upstream version 4.9.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#833762)
The nss-util package has been upgraded to upstream version 3.13.5, which provides a number of bug fixes and enhancements over the previous version. (BZ#833763)
The nss package has been upgraded to upstream version 3.13.5, which provides a number of bug fixes and enhancements over the previous version. (BZ#834100)
All NSS, NSPR, and nss-util users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. After installing this update, applications using NSS, NSPR, or nss-util must be restarted for this update to take effect.
