Vendor and ecosystem advisories describing this.

SSA-595101SSA-595101: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.2.0.52021-12-14csaf · siemens_psirtDE
Siemens has released version V13.2.0.5 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read maliciously crafted files in different file formats (PDF, JT, TIFF, CGM and TIF). If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.
SSA-936212SSA-936212: JT File Parsing Vulnerabilities in JT Open, JT Utilities and Solid Edge2023-01-10csaf · siemens_psirtDE
JT Open Toolkit, JT Utilities and Solid Edge are affected by memory corruption vulnerabilities that could be triggered while parsing JT files. If a user is tricked to open a malicious JT file with any of the affected products, this could cause the application to crash or potentially lead to arbitrary code execution. Siemens has released updates for the affected products and recommends to update to the latest versions.
