3. Description:

 

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

generic in nature, but intended for use in speeding up dynamic web

applications by alleviating database load.

 

Security Fix(es):

 

* Two integer overflow flaws, leading to heap-based buffer overflows, were

found in the memcached binary protocol. An attacker could create a

specially crafted message that would cause the memcached server to crash

or, potentially, execute arbitrary code. (CVE-2016-8704, CVE-2016-8705)
