USN-3120-1: Memcached vulnerabilities

2 November 2016

Memcached could be made to crash or run programs if it received specially crafted network traffic.



  • memcached - A high-performance memory object caching system


Aleksandar Nikolic discovered that Memcached incorrectly handled certain
malformed commands. A remote attacker could use this issue to cause
Memcached to crash, resulting in a denial of service, or possibly execute
arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.10
Ubuntu 16.04
Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
