Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the try_read_command function in memcached.c in memcached before 1.4.39. A remote attacker can perform 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.
Remediation
Update to version 1.4.39
