`memjs` versions <= 1.1.0 allocates and stores buffers on typed input, resulting in DoS and uninitialized memory usage.

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.

PHPMemcachedAdmin 1.2.2 and earlier allows remote attackers to execute arbitrary PHP code via vectors related "serialized data and the last part of the concatenated filename," which creates a file in webroot.

An integer overflow in the process_bin_append_prepend function in Memcached, which is responsible for processing multiple commands of Memcached binary protocol, can be abused to cause heap overflow and lead to remote code execution.

Multiple integer overflows in process_bin_update function in Memcached, which is responsible for processing multiple commands of Memcached binary protocol, can be abused to cause heap overflow and lead to remote code execution.

An integer overflow in process_bin_sasl_auth function in Memcached, which is responsible for authentication commands of Memcached binary protocol, can be abused to cause heap overflow and lead to remote code execution.

Cross-site scripting (XSS) vulnerability in phpMemcachedAdmin 1.2.2 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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.
