CVE-2019-15892 (opens in a new tab)How to fix?
Upgrade Debian:11 varnish to version 6.2.1-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream varnish package and not the varnish package as distributed by Debian.
See How to fix? for Debian:11 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.
