In memcached before 1.5.14, a NULL pointer dereference was found in the "lru mode" and "lru temp_ttl" commands
CVE-2019-11596
7.5 - High
- April 29, 2019

memcached version prior to 1.4.37 contains an Integer Overflow vulnerability in items.c:item_free()
CVE-2018-1000127
7.5 - High
- March 13, 2018
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.
Integer Overflow or Wraparound
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
