Ubuntu 8.04 LTS / 8.10 / 9.04 : dnsmasq vulnerabilities (USN-827-1)

medium Nessus Plugin ID 40848

Synopsis

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

Description

IvAin Arce, Pablo HernAin Jorge, Alejandro Pablo Rodriguez, MartAn Coco, Alberto SoliAto Testa and Pablo Annetta discovered that Dnsmasq did not properly validate its input when processing TFTP requests for files with long names. A remote attacker could cause a denial of service or execute arbitrary code with user privileges. Dnsmasq runs as the 'dnsmasq' user by default on Ubuntu. (CVE-2009-2957)

Steve Grubb discovered that Dnsmasq could be made to dereference a NULL pointer when processing certain TFTP requests. A remote attacker could cause a denial of service by sending a crafted TFTP request.
(CVE-2009-2958).

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 dnsmasq and / or dnsmasq-base packages.
