Ubuntu 8.04 LTS / 9.04 / 9.10 / 10.04 LTS : gnupg2 vulnerability (USN-970-1)

medium Nessus Plugin ID 48315

Language:

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

It was discovered that GPGSM in GnuPG2 did not correctly handle certificates with a large number of Subject Alternate Names. If a user or automated system were tricked into processing a specially crafted certificate, an attacker could cause a denial of service or execute arbitrary code with privileges of the user invoking the program.

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 gnupg-agent, gnupg2 and / or gpgsm packages.
