A vulnerability has been identified in JT2Go (All versions < V13.1.0.3), Teamcenter Visualization (All versions < V13.1.0.3). The TIFF_loader.dll library in affected applications lacks proper validation of user-supplied data when parsing TIFF files. This could result in an out of bounds write past the end of an allocated structure. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13131)

Vendor and ecosystem advisories describing this.

SSA-645530SSA-645530: TIFF File Parsing Vulnerability in JT2Go and Teamcenter Visualization before V13.1.0.32021-06-08csaf · siemens_psirtDE
Siemens has released version V13.1.0.3 for JT2Go and Teamcenter Visualization to fix a vulnerability that could be triggered when the products read files in TIFF file format. 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.
