Synopsis
========

Multiple vulnerabilities have been found in memcached, allowing remote
attackers to execute arbitrary code or cause Denial of Service.

Background
==========

memcached is a high-performance, distributed memory object caching
system

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/memcached           < 1.4.17                  >= 1.4.17

Description
===========

memcached authentication could be bypassed when using SASL due to a
flaw related to SASL authentication state. Also several heap-based
buffer overflows due to integer conversions when parsing certain length
attributes were discovered.

Impact
======

A remote attacker could possibly execute
arbitrary code with the privileges of the process, cause a Denial of
Service condition or authenticate with invalid SASL credentials,
bypassing memcached authentication completely.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All memcached users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-misc/memcached-1.4.17"
