CVE-2020-26980
Estado: ModificadaAlta (8.8)—
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 JT files. A crafted JT file could trigger a type confusion condition. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-11881)
