Memcached 1.4.39 Release Notes

Date: 2017-7-4



Fixes a reported CVE in binary protocol code. Also adds a trivial 4 byte reduction in memory usage under -o modern if client flags aren't used.

This CVE seems relatively minor; may be able to crash worker threads. I wasn't able to quickly reproduce a crash but folks should still upgrade when convenient.


  • fix for CVE-2017-9951
  • save four bytes per item if client flags are 0

New Features

If client flags are "0", no extra storage is used.
