Memcached: Security Vulnerabilities
memcached version prior to 1.4.37 contains an Integer Overflow vulnerability in items.c:item_free() that can result in data corruption and deadlocks due to items existing in hash table being reused from free list. This attack appear to be exploitable via network connectivity to the memcached service. This vulnerability appears to have been fixed in 1.4.37 and later.

Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.

The try_read_command function in memcached.c in memcached before 1.4.39 allows remote attackers to cause a denial of service (segmentation fault) via a request to add/set a key, which makes a comparison between signed and unsigned int and triggers a heap-based buffer over-read. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-8705.

The process_bin_delete function in memcached.c in memcached 1.4.4 and other versions before 1.4.17, when running in verbose mode, allows remote attackers to cause a denial of service (segmentation fault) via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers a buffer over-read when printing to stderr.
