MEMCACHED SERVER APPEND/PREPEND REMOTE CODE EXECUTION VULNERABILITY
The MITRE CVE dictionary describes this issue as:
An integer overflow flaw, leading to a heap-based buffer overflow, was 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.
9.8 – CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
This flaw is in the memcached binary protocol. If you client programs only use the ASCII protocol when communicating with memcached, you can disable the binary protocol and protect against this flaw by adding “-B ascii” to OPTIONS in /etc/sysconfig/memcached.
