NVD Description

Note: Versions mentioned in the description apply only to the upstream squid:4/squid package and not the squid:4/squid 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 a buffer-management bug, it allows a denial of service. When resolving a request with the urn: scheme, the parser leaks a small amount of memory. However, there is an unspecified attack methodology that can easily trigger a large amount of memory consumption.
