CVE-2020-26996: Siemens JT2Go CG4 File Parsing Out-Of-Bounds Read Remote Code Execution Vulnerability
A vulnerability has been identified in JT2Go (All versions < V13.1.0), Teamcenter Visualization (All versions < V13.1.0). Affected applications lack proper validation of user-supplied data when parsing of CG4 files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-12027)
