TITLE

JT2Go and Teamcenter Visualization Input confirmation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-009335

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). 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 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-13198). JT2Go and Teamcenter Visualization There are input validation and out-of-bounds read vulnerabilities. Zero Day Initiative To this vulnerability ZDI-CAN-13198 Was numbered.Information may be obtained. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of TIFF files
