Description

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.
