Red Hat: RHSA-2011:1282-01 Important: nss and nspr Certificate Trust Issue

red hat
Calendar Grey September 12, 2011
Dist Redhat Esm H88
Red Hat has issued a significant security advisory highlighting enhancements for nss and nspr, addressing vulnerabilities related to certificate validation across multiple RHEL iterations.
Updated nss and nspr packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6

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/kb/docs/DOC-11259

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.
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.
These updated packages upgrade NSS to version 3.12.10 on Red Hat Enterprise Linux 4 and 5. As well, they upgrade NSPR to version 4.8.8 on Red Hat Enterprise Linux 4 and 5, as required by the NSS update. The packages for Red Hat Enterprise Linux 6 include a backported patch.
All NSS and NSPR users should upgrade to these updated packages, which correct this issue. After installing the update, applications using NSS and NSPR must be restarted for the changes to take effect.
