A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The BMP_Loader.dll library in affected applications lacks proper validation of user-supplied data when parsing BMP files. This could result in an out of bounds read past the end of an allocated buffer. An attacker could leverage this vulnerability to leak information in the context of the current process. (ZDI-CAN-13197)

- SSA-483182SSA-483182: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.22021-07-13csaf · siemens_psirtDE
Siemens has released version V13.2 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in different file formats (GIF, TIFF, BMP, J2K, JT, SGI, PDF, PCT, PCX, PAR and ASM ). 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 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.
