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)
