Moderate: varnish:6 security, bug fix, and enhancement update
Varnish Cache is a high-performance HTTP accelerator. It stores web pages in memory so web servers don't have to create the same web page over and over again, giving the website a significant speed up.
The following packages have been upgraded to a later upstream version: varnish (6.0.6). (BZ#1795673)
Security Fix(es):
-
varnish: denial of service handling certain crafted HTTP/1 requests (CVE-2019-15892)
-
varnish: remote clients may cause Varnish to assert and restart which could result in DoS (CVE-2020-11653)
-
varnish: not clearing pointer between two client requests leads to information disclosure (CVE-2019-20637)

ELSA-2020-4756: varnish:6 security, bug fix, and enhancement update (MODERATE)
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.
