The remote Ubuntu 22.04 LTS / 23.04 / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6551-1 advisory.

  • An issue was discovered in the function gdev_prn_open_printer_seekable() in Artifex Ghostscript through 10.02.0 allows remote attackers to crash the application via a dangling pointer. (CVE-2023-46751)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
