CVE-2022-41662

Code execution via malformed CGM parsing

Published Nov 8, 2022 · Updated Apr 21, 2025

Out-of-bounds read in Siemens JT2Go and Teamcenter Visualization allows attackers to execute code via a crafted CGM file. In affected releases—JT2Go before 14.1.0.4 and Teamcenter Visualization before the listed branch-specific fixes—the CGM parser reads beyond an allocated buffer while processing malformed file data; Siemens has not disclosed the specific routine or field. Execution requires a user to open an untrusted CGM file, and resulting code runs with the current process's privileges; the same parsing fault can instead crash the application.
