Name of the Vulnerable Software and Affected Versions ghostscript version 9.07

Description An issue was discovered where a previous fix did not fully address the problem, allowing an attacker to potentially exploit a variant of the flaw.

Recommendations For ghostscript version 9.07, consider applying additional security measures to prevent the exploitation of this issue, such as restricting access to PostScript documents from untrusted sources, until a comprehensive fix is available.
