Vulnerability Name:

CVE-2019-15892 (CCN-166529)

Assigned:2019-09-03
Published:2019-09-03
Updated:2022-08-02
Summary: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.
