CVE-2019-11596 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream memcached package and not the memcached package as distributed by Debian.
In memcached before 1.5.14, a NULL pointer dereference was found in the "lru mode" and "lru temp_ttl" commands. This causes a denial of service when parsing crafted lru command messages in process_lru_command in memcached.c.
