RHEL 7 : memcached (RHSA-2016:2819)

critical Nessus Plugin ID 95291

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2819 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL memcached package based on the guidance in RHSA-2016:2819.
