Security Bulletin
Summary
Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. The nss-util packages provide utilities for use with the Network Security Services (NSS) libraries. Netscape Portable Runtime (NSPR)
provides platform independence for non-GUI operating system facilities.
IBM Security Access Manager for Mobile uses NSS and is affected by two use-after-free flaws that have been identified in the NSS libraries.
