Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. It was found that a Certificate Authority (CA) issued fraudulent HTTPS certificates. This update renders any HTTPS certificates signed by that CA as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code signing. Updated packages are available from ftp.redhat.com.

Summary: Updated nss packages that fix one security issue are now available for Red Hat Enterprise Linux 5.6 Extended Update Support The Red Hat Security Response Team has rated this update as having important security impact. 2. Relevant releases/architectures: Red Hat Enterprise Linux EUS (v. 5.6 server) - i386, ia64, ppc, s390x, 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. It was found that a Certificate Authority (CA) issued fraudulent HTTPS certificates. This update renders any HTTPS certificates signed by that CA as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code signing. (BZ#734316) 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. All NSS users should upgrade to these updated packages, which correct this issue. After installing the update, applications using NSS 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. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5.
