NVD Description
Note: Versions mentioned in the description apply only to the upstream squid-debugsource package and not the squid-debugsource package as distributed by RHEL.
An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to an input-validation bug, it is vulnerable to a Denial of Service attack (against all clients using the proxy). A client sends an HTTP Range request to trigger this.
