DLA-1033-1 memcached -- LTS security update

Date Reported:

20 Jul 2017

Affected Packages:

memcached

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2017-9951.

More information:

It was discovered that there was a remote denial-of-service (DoS) vulnerability in memcached, a high-performance memory object caching system.

The try_read_command function allowed remote attackers to cause a DoS via a request to add/set a key that makes a comparison between a signed and unsigned integer which triggered a heap-based buffer over-read.

This vulnerability existed due to an incomplete upstream fix for CVE-2016-8705.

For Debian 7 Wheezy, this issue has been fixed in memcached version 1.4.13-0.2+deb7u3.

We recommend that you upgrade your memcached packages.
