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.

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."
