Issue Overview:

A flaw was found in the way libtasn1 decoded DER data. An attacker could create carefully-crafted DER encoded input (such as an X.509 certificate) that, when parsed by an application that uses libtasn1 (such as applications using GnuTLS), could cause the application to crash. (CVE-2012-1569)

Affected Packages:

libtasn1

Issue Correction:
Run yum update libtasn1 to update your system.
