Debian DSA-2832-1 : memcached - several vulnerabilities

medium Nessus Plugin ID 71780

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Multiple vulnerabilities have been found in memcached, a high-performance memory object caching system. The Common Vulnerabilities and Exposures project identifies the following issues :

- CVE-2011-4971 Stefan Bucur reported that memcached could be caused to crash by sending a specially crafted packet.

- CVE-2013-7239 It was reported that SASL authentication could be bypassed due to a flaw related to the managment of the SASL authentication state. With a specially crafted request, a remote attacker may be able to authenticate with invalid SASL credentials.

Solution

Upgrade the memcached packages.

For the oldstable distribution (squeeze), these problems have been fixed in version 1.4.5-1+deb6u1. Note that the patch for CVE-2013-7239 was not applied for the oldstable distribution as SASL support is not enabled in this version. This update also provides the fix for CVE-2013-0179 which was fixed for stable already.

For the stable distribution (wheezy), these problems have been fixed in version 1.4.13-0.2+deb7u1.
