CVE-2017-9951 (opens in a new tab)How to fix?
There is no fixed version for RHEL:7 memcached-devel.
NVD Description
Note: Versions mentioned in the description apply only to the upstream memcached-devel package and not the memcached-devel package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
