Detail

Problem Description:

Updated nss and nspr packages that fix one security issue, various bugs, and add enhancements are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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.

It was found that a Certificate Authority (CA) mis-issued two intermediate certificates to customers. These certificates could be used to launch man-in-the-middle attacks. This update renders those certificates as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code signing. (BZ#890605)

In addition, the nss package has been upgraded to upstream version 3.13.6, and the nspr package has been upgraded to upstream version 4.9.2. These updates provide a number of bug fixes and enhancements over the previous versions. (BZ#893371, BZ#893372)

All NSS and NSPR users should upgrade to these updated packages, which correct these issues and add these enhancements. After installing the update, applications using NSS and NSPR must be restarted for the changes to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
