A vulnerability has been identified in JT2Go (All versions < V13.1.0), Teamcenter Visualization (All versions < V13.1.0). Affected applications lack proper validation of user-supplied data when parsing of TGA files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12016, ZDI-CAN-12017)

Vendor and ecosystem advisories describing this.

SSA-622830SSA-622830: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.1.02021-01-12csaf · siemens_psirtDE
Siemens has released version V13.1.0 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in different file formats (JT, XML, CG4, CGM, PDF, RGB, SGI, TGA, PAR, PCX). If a user is tricked to opening of a malicious file with the affected products, this could lead to application crash, or potentially arbitrary code execution or data extraction on the target host system. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products. Please refer to SSA-663999 [0] and SSA-695540 [1] for further information regarding later version updates. Note: Previous versions of this advisory also contained the vulnerabilities CVE-2020-26989, CVE-2020-26990, and CVE-2020-28383 (now addressed in [0]) and CVE-2020-26991 (now addressed in [1]).
