**Name of the Vulnerable Software and Affected Versions** CUPS versions prior to 1.1.19 **Description** The issue is related to the Internet Printing Protocol (IPP) implementation in CUPS, which allows remote attackers to cause a denial of service via certain inputs to the IPP port (TCP 631). This can lead to CPU consumption from a "busy loop". Additionally, there are multiple vulnerabilities in the CUPS package of Red Hat Linux that can be exploited remotely, potentially disrupting the confidentiality, integrity, and availability of protected information. **Recommendations** For versions prior to 1.1.19, update to version 1.1.19 or later to resolve the issue. As a temporary workaround, consider restricting access to the IPP port (TCP 631) to minimize the risk of exploitation.
