NVD Description

Note: Versions mentioned in the description apply only to the upstream varnish-modules package and not the varnish-modules package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8.
