Name of the Vulnerable Software and Affected Versions Ghostscript versions prior to 9.51

Description The issue is related to a division by zero error in the dot24 print page() function, located in devices/gdevdm24.c, which can be exploited by a remote attacker to cause a denial of service. This can be achieved through a crafted PDF file.

Recommendations For Ghostscript versions prior to 9.51, update to version 9.51 or later to resolve the issue. As a temporary workaround, consider restricting the use of the dot24 print page() function until a patch is available. Avoid processing untrusted or crafted PDF files with affected versions of Ghostscript to minimize the risk of exploitation.
