GHSA-VPCM-5GWM-79H2

Vulnerability from github – Published: 2022-05-13 01:48 – Updated: 2025-04-20 03:40

Details

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.

Severity ?

7.5 (High)
