Synopsis

The remote CentOS 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.
