Description GLSAMaker/CVETool Bot gentoo-dev 2018-08-05 22:56:14 UTC
CVE-2018-1000127 (
  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.
