CVE-2021-34304: Siemens JT2Go TIF File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The TiffLoader.dll library in affected applications lacks proper validation of user-supplied data when parsing TIFF 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-13199)
