===================================================================== Red Hat Security Advisory
Synopsis: Moderate: varnish:6 security, bug fix, and enhancement update Advisory ID: RHSA-2020:4756-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2020:4756 Issue date: 2020-11-03 CVE Names: CVE-2019-15892 CVE-2019-20637 CVE-2020-11653 =====================================================================
1. Summary:
An update for the varnish:6 module is now available for Red Hat Enterprise Linux 8.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AppStream (v. 8) - aarch64, ppc64le, s390x, x86_64
3. 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)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
