RHSA-2023:3403: Red Hat Security Advisory: pcs security and bug fix update

An update for pcs is now available for Red Hat Enterprise Linux 8.6 Extended Update Support. 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.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

Related CVEs:

  • CVE-2023-27530: A flaw was found in rubygem-rack. This issue occurs in the Multipart MIME parsing code in Rack, which limits the number of file parts but does not limit the total number of parts that can be uploaded. Carefully crafted requests can abuse this and cause multipart parsing to take longer than expected, resulting in a denial of service.
  • CVE-2023-27539: A denial of service vulnerability was found in rubygem-rack in how it parses headers. A carefully crafted input can cause header parsing to take an unexpected amount of time, possibly resulting in a denial of service.
