Summary
cups vulnerability
Details
Johannes Meixner and Paul Zirnik discovered that CUPS incorrectly handled clients that send messages slowly. A remote attacker could possibly use this issue to cause CUPS to stop responding, resulting in a denial of service. (CVE-2025-58436)
In addition, this update fixes a regression introduced in USN-7897-1 which resulted in certain invalid configuration file directives to cause the CUPS daemon to fail to start.
