"Multiple vulnerabilites have been found in memcached, a
high-performance memory object caching system. A remote attacker could
take advantage of these flaws to cause a denial of service (daemon
crash), or potentially to execute arbitrary code.  

CVE-2013-7291

It was discovered that memcached, when running in verbose mode, can be
crashed by sending carefully crafted requests that trigger an
unbounded key print, resulting in a daemon crash.

CVE-2016-8704, CVE-2016-8705, CVE-2016-8706

Aleksandar Nikolic of Cisco Talos found several vulnerabilities in
memcached. A remote attacker could cause an integer overflow by
sending carefully crafted requests to the memcached server, resulting
in a daemon crash.

For Debian 7 'Wheezy', these problems have been fixed in version
1.4.13-0.2+deb7u2.

We recommend that you upgrade your memcached packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
