cups: Fix CVE-2023-32324

OpenPrinting CUPS is an open source printing system. In versions 2.4.2
and prior, a heap buffer overflow vulnerability would allow a remote
attacker to launch a denial of service (DoS) attack. A buffer overflow
vulnerability in the function `format_log_line` could allow remote
attackers to cause a DoS on the affected system. Exploitation of the
vulnerability can be triggered when the configuration file `cupsd.conf`
sets the value of `loglevel `to `DEBUG`. No known patches or
workarounds exist at time of publication.
