Title:CentOS Update for libtasn1 CESA-2012:0427 centos6
Summary:The remote host is missing an update for the 'libtasn1'; package(s) announced via the referenced advisory.
The remote host is missing an update for the 'libtasn1'
package(s) announced via the referenced advisory.

Vulnerability Insight:
libtasn1 is a library developed for ASN.1 (Abstract Syntax Notation One)
structures management that includes DER (Distinguished Encoding Rules)
encoding and decoding.

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.

Red Hat would like to thank Matthew Hall of Mu Dynamics for reporting this

Users of libtasn1 are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For the update to take
effect, all applications linked to the libtasn1 library must be restarted,
or the system rebooted.

Affected Software/OS:
libtasn1 on CentOS 6

Please install the updated packages.
