Debian DLA-1033-1 : memcached security update

high Nessus Plugin ID 101856

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a remote denial of service (DoS) vulnerability in memcached, a high-performance memory object caching system.

The try_read_command function allowed remote attackers to cause a DoS via a request to add/set a key that makes a comparison between a signed and unsigned integer which triggered a heap-based buffer over-read.

This vulnerability existed due to an incomplete upstream fix for CVE-2016-8705.

For Debian 7 'Wheezy', this issue has been fixed in memcached version 1.4.13-0.2+deb7u3.

We recommend that you upgrade your memcached 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 memcached package.
