Memcached: Security Vulnerabilities
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.

memcached before 1.4.17 allows remote attackers to bypass authentication by sending an invalid request with SASL credentials, then sending another request with incorrect SASL credentials.

The do_item_get function in items.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, a different vulnerability than CVE-2013-0179.

memcached before 1.4.17, when running in verbose mode, allows remote attackers to cause a denial of service (crash) via a request that triggers an "unbounded key print" during logging, related to an issue that was "quickly grepped out of the source tree," a different vulnerability than CVE-2013-0179 and CVE-2013-7290.

Multiple integer signedness errors in the (1) process_bin_sasl_auth, (2) process_bin_complete_sasl_auth, (3) process_bin_update, and (4) process_bin_append_prepend functions in Memcached 1.4.5 and earlier allow remote attackers to cause a denial of service (crash) via a large body length value in a packet.
