Debian DLA-701-1 : memcached security update

critical Nessus Plugin ID 94584

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected memcached package.
