Debian DSA-3220-1 : libtasn1-3 - security update

critical Nessus Plugin ID 82721

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Hanno Boeck discovered a stack-based buffer overflow in the asn1_der_decoding function in Libtasn1, a library to manage ASN.1 structures. A remote attacker could take advantage of this flaw to cause an application using the Libtasn1 library to crash, or potentially to execute arbitrary code.

Solution

Upgrade the libtasn1-3 packages.

For the stable distribution (wheezy), this problem has been fixed in version 2.13-2+deb7u2.
