CVE-2019-15892 (GCVE-0-2019-15892)

Vulnerability from cvelistv5 – Published: 2019-09-03 20:56 – Updated: 2024-08-05 01:03
VLAI
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.
