MEMCACHED SERVER SASL AUTENTICATION REMOTE CODE EXECUTION VULNERABILITY
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.
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.
