Description
This security bulletin contains information about 1 security vulnerability.
1) Buffer over-read (CVE-ID: CVE-2017-9951)
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.
