Name of the Vulnerable Software and Affected Versions
Artifex Ghostscript versions prior to 9.24
Description
The issue is related to the .setdistillerkeys PostScript command, which is accepted even though it is not intended for use during document processing. This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact.
Recommendations
For Artifex Ghostscript versions prior to 9.24, update to version 9.24 or later to resolve the issue. As a temporary workaround, consider restricting the use of the .setdistillerkeys PostScript command to minimize the risk of exploitation.
