NVD Description
Note: Versions mentioned in the description apply only to the upstream rh-varnish6-varnish package and not the rh-varnish6-varnish package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
An issue was discovered in Varnish Cache before 6.0.4 LTS, and 6.1.x and 6.2.x before 6.2.1. An HTTP/1 parsing failure allows a remote attacker to trigger an assert by sending crafted HTTP/1 requests. The assert will cause an automatic restart with a clean cache, which makes it a Denial of Service attack.
