NVD Description

Note: Versions mentioned in the description apply only to the upstream squid3 package and not the squid3 package as distributed by Ubuntu.

An issue was discovered in Squid before 4.15 and 5.x before 5.0.6. An integer overflow problem allows a remote server to achieve Denial of Service when delivering responses to HTTP Range requests. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent.
