Synopsis

The remote Debian host is missing a security update.

Description

Samuel R Lovejoy discovered a security vulnerability in dnsmasq.
Carefully crafted packets by DNS servers might result in out of bounds read operations, potentially leading to a crash and denial of service.

For Debian 8 'Jessie', this problem has been fixed in version 2.72-3+deb8u5.

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.
