TITLE

JT2Go and Teamcenter Visualization Input confirmation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2021-009318

DESCRIPTION

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 PCT 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-13403). JT2Go and Teamcenter Visualization Is vulnerable to input validation. Zero Day Initiative To this vulnerability ZDI-CAN-13403 Was numbered.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. 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 PCT 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
