      <Note Title="Vulnerability Description" Type="General" Ordinal="1" xml:lang="en">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.
