CVE-2021-27396

A vulnerability has been identified in Tecnomatix Plant Simulation (All versions < V16.0.5). The PlantSimCore.dll library lacks proper validation of user-supplied data when parsing SPP files. This could result in a stack based buffer overflow, a different vulnerability than CVE-2021-27398. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13279)
