NVD Description

Note: Versions mentioned in the description apply only to the upstream squid:4/libecap-devel package and not the squid:4/libecap-devel package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. Due to incorrect parser validation, it allows a Denial of Service attack against the Cache Manager API. This allows a trusted client to trigger memory leaks that. over time, lead to a Denial of Service via an unspecified short query string. This attack is limited to clients with Cache Manager API access privilege.
