NVD Description

Note: Versions mentioned in the description apply only to the upstream squid-sysvinit package and not the squid-sysvinit package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).
