Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.04 : gnupg, gnupg2 vulnerabilities (USN-1987-1)

medium Nessus Plugin ID 70366

Synopsis

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

Description

Daniel Kahn Gillmor discovered that GnuPG treated keys with empty usage flags as being valid for all usages. (CVE-2013-4351)

Taylor R Campbell discovered that GnuPG incorrectly handled certain OpenPGP messages. If a user or automated system were tricked into processing a specially crafted message, GnuPG could consume resources, resulting in a denial of service. (CVE-2013-4402).

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 and / or gnupg2 packages.
