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

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."
