Name of the Vulnerable Software and Affected Versions: JT Utilities versions prior to 13.0.2.0

Description: A issue has been identified that causes the application to crash when parsing specially crafted JT files due to a missing check for the validity of an iterator, leading to a NULL pointer deference condition. This can be leveraged to cause a Denial-of-Service condition in the application.

Recommendations: For versions prior to 13.0.2.0, update to version 13.0.2.0 or later to resolve the issue. As a temporary workaround, consider restricting the parsing of JT files from untrusted sources until a patch is applied.
