CWEhttps://cwe.mitre.org/data/definitions/755.html

A flaw was found in Squid. The limits applied for validation of HTTP response headers are applied before caching. However, Squid may grow a cached HTTP response header beyond the configured maximum size, causing a stall or crash of the worker process when a large header is retrieved from the disk cache, resulting in a denial of service.

Weakness

The product does not handle or incorrectly handles an exceptional condition.
