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.
