Scientific Linux Security Update : nss, nss-util, and nspr on SL6.x i386/x86_64

High Nessus Plugin ID 64427


The remote Scientific Linux host is missing one or more security updates.


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.

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.

After installing this update, applications using NSS, NSPR, or nss-util must be restarted for this update to take effect.


Update the affected packages.
