Ubuntu 8.04 LTS / 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : libtasn1-3 vulnerability (USN-1436-1)

medium Nessus Plugin ID 58974

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Matthew Hall discovered that Libtasn incorrectly handled certain large values. An attacker could exploit this with a specially crafted ASN.1 structure and cause a denial of service, or possibly execute arbitrary code.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libtasn1-3 package.
