Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

An update for memcached is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)
