NVD Description

Note: Versions mentioned in the description apply only to the upstream squid package and not the squid package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

An issue was discovered in Squid 5.0.6 through 5.1.x before 5.2. When validating an origin server or peer certificate, Squid may incorrectly classify certain certificates as trusted. This problem allows a remote server to obtain security trust well improperly. This indication of trust may be passed along to clients, allowing access to unsafe or hijacked services.
