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)
* 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. (CVE-2016-8706)
