Scientific Linux Security Update : libtasn1 on SL6.x i386/x86_64 (20120327)

medium Nessus Plugin ID 61292

Language:

Synopsis

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

Description

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. (CVE-2012-1569)

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.

Solution

Update the affected packages.
