TITLE

JT2Go and Teamcenter Visualization Out-of-bounds read vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-009285

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The Jt981.dll library in affected applications lacks proper validation of user-supplied data when parsing JT 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-13406). JT2Go and Teamcenter Visualization There is a vulnerability related to out-of-bounds reading and a vulnerability related to input verification. Zero Day Initiative To this vulnerability ZDI-CAN-13406 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 JT files. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements
