CentOS Errata and Security Advisory CESA-2016:2819

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)
