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 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme.
