red hat
Calendar Grey December 19, 2013
Dist Redhat Esm H88
Alert notification from Red Hat: Important nss patch mitigates unauthorized interception threats in business infrastructures.
Updated nss packages that fix one security issue are now available for Red Hat Enterprise Linux 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/site/articles/11258

Summary

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 subordinate Certificate Authority (CA) mis-issued an intermediate certificate, which could be used to conduct man-in-the-middle attacks. This update renders that particular intermediate certificate as untrusted. (BZ#1038894)
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.
