NVD Description

Note: Versions mentioned in the description apply only to the upstream squid package and not the squid package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs because unrecognized error values are mapped to NULL, but later code expects that each error value is mapped to a valid error string.
