CVE-2016-8706

An integer overflow flaw, leading to a heap-based buffer overflow, was found in memcached's parsing of SASL authentication messages. An attacker could create a specially crafted message that would cause the memcached server to crash or, potentially, execute arbitrary code.

The version of memcached as shipped with Red Hat OpenStack Platform 9 is affected by this issue however will not be updated. The latest version of memcached from Red Hat Enterprise Linux 7 can safely be allowed to supersede the earlier versions provided in the Red Hat OpenStack Platform channels.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

This flaw requires memcached to be running with SASL authentication enabled, which is not the default setting. If your memcached instances are running without the "-S" command-line option, they are not vulnerable.
