CVE-2017-9951 (GCVE-0-2017-9951)

Vulnerability from cvelistv5

Published

2017-07-17 06:00

Modified

2024-08-05 17:24

Severity ?

CWE

Summary

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.
