A moderate severity open redirect vulnerability (CVE-2024-21510) exists in the pcs packages used for configuring Pacemaker and Corosync utilities on Red Hat Enterprise Linux 8. The vulnerability is due to improper handling of the X-Forwarded-Host header in the Sinatra framework. Red Hat has released security updates to address this issue in multiple variants of Red Hat Enterprise Linux 8 High Availability and Resilient Storage products.

A denial-of-service (DoS) vulnerability exists in the python-tornado package used by the pcs command-line configuration system for Pacemaker and Corosync utilities. The issue involves HTTP cookie parsing in Tornado, which could be exploited to cause service disruption. Red Hat has issued security advisories for Red Hat Enterprise Linux 8.8 and 9.2 Extended Update Support releases, providing updated packages to address this vulnerability.

The pcs packages provide a command-line configuration system for the Pacemaker and Corosync utilities. Security Fix(es): * rexml: rubygem-rexml: DoS when parsing an XML having many specific characters such as whitespace character, >] and ]> (CVE-2024-41123) * rexml: DoS vulnerability in REXML (CVE-2024-41946) * rexml: DoS vulnerability in REXML (CVE-2024-43398) 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.

A low severity vulnerability (CVE-2024-35176) affects the pcs packages used for command-line configuration of Pacemaker and Corosync utilities in Red Hat Enterprise Linux 8. The issue involves a denial of service (DoS) caused by the REXML parser when processing XML attributes containing many '<' characters. Red Hat has released an update to address this vulnerability in multiple Red Hat Enterprise Linux 8 variants, including High Availability and Resilient Storage editions across various architectures. No known exploits are reported in the wild. The update is available and should be applied to affected systems.
