CVE-2022-39136

Code execution via crafted TIF heap overflow

Published Nov 8, 2022 · Updated Apr 21, 2025

Heap-based buffer overflow in Siemens JT2Go and Teamcenter Visualization allows attackers to execute code through a crafted TIF file. During parsing, TIF-controlled data overruns a fixed-length heap buffer; Siemens does not identify the parser routine or malformed field. Exploitation requires a user to open the file, and successful code runs with the privileges of the affected application process.
