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.
