Red Hat: 2011:0472-01 Important: NSS Certificate Compromise Advisory

red hat
Calendar Grey April 29, 2011
Dist Redhat Esm H88
Debian's critical TLS patch resolves vulnerabilities related to flawed authentication. Immediate installation is vital for safeguarding.
Updated nss 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 development of security-enabled client and server applications.
This erratum blacklists a small number of HTTPS certificates by adding them, flagged as untrusted, to the NSS Builtin Object Token (the libnssckbi.so library) certificate store. (BZ#689430)
Note: This fix only applies to applications using the NSS Builtin Object Token. It does not blacklist the certificates for applications that use the NSS library, but do not use the NSS Builtin Object Token (such as curl).
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.
