Insight
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)
Note: This fix only applies to applications using the NSS Builtin Object Token. It does not render the certificates untrusted for applications that use the NSS library, but do not use the NSS Builtin Object Token.
In addition, the nss package has been upgraded to upstream version 3.13.6, the nss-util 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#891663, BZ#891670, BZ#891661)
Users of NSS, NSPR, and nss-util are advised to upgrade to these updated packages, which fix 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.
Affected
nss, nss-util, and nspr on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)
