| Revision Date: | 2020-11-04 | Version: | 636 | | Title: | RHSA-2020:4756: varnish:6 security, bug fix, and enhancement update (Moderate) | | Description: | 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)
