Summary
It was discovered that there was a remote denial-of-service (DoS) vulnerability in memcached, a high-performance memory object caching system. The try_read_command function allowed remote attackers to cause a DoS via a request to add/set a key that makes a comparison between a signed and unsigned integer which triggered a heap-based buffer over-read. This vulnerability existed due to an incomplete upstream fix for CVE-2016-8705.
