  • CVE-2023-2319: It was discovered that an update for PCS package in RHBA-2023:2151 erratum released as part of Red Hat Enterprise Linux 9.2 failed to include the fix for the Webpack issue CVE-2023-28154 (for PCS package), which was previously addressed in Red Hat Enterprise Linux 9.1 via erratum RHSA-2023:1591. The CVE-2023-2319 was assigned to that Red Hat specific security regression in Red Hat Enterprise Linux 9.2.
  • 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.
