memcached - several

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.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your memcached packages.
