Debian DLA-1124-1 : dnsmasq security update

High Nessus Plugin ID 103709

Synopsis

The remote Debian host is missing a security update.

Description

Felix Wilhelm, Fermin J. Serna, Gabriel Campana, Kevin Hamacher, Ron Bowes and Gynvael Coldwind of the Google Security Team discovered several vulnerabilities in dnsmasq, a small caching DNS proxy and DHCP/TFTP server, which may result in denial of service, information leak or the execution of arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 2.62-3+deb7u4.

We recommend that you upgrade your dnsmasq packages.

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

Solution

Upgrade the affected packages.
