Ubuntu Security Notice USN-3588-1
March 05, 2018

memcached vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 17.10
- - Ubuntu 16.04 LTS
- - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Memcached.

Software Description:
- - memcached: high-performance memory object caching system

Details:

Daniel Shapira discovered an integer overflow issue in Memcached. A remote
attacker could use this to cause a denial of service (daemon crash).
(CVE-2017-9951)

It was discovered that Memcached listened to UDP by default. A remote
attacker could use this as part of a distributed denial of service attack.
(CVE-2018-1000115)

Update instructions:

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

Ubuntu 17.10:
  memcached                       1.4.33-1ubuntu3.2

Ubuntu 16.04 LTS:
  memcached                       1.4.25-2ubuntu1.3

Ubuntu 14.04 LTS:
  memcached                       1.4.14-0ubuntu9.2

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

Please note that after applying this update, Memcached will no longer
listen to UDP by default. If UDP service is desired, please add
'-U 11211' to /etc/memcached.conf and restart the memcached service.
