"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."
