Descriptions
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 prior to performing further free operations on an object when parsing JT files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13430)
Se ha identificado una vulnerabilidad en JT2Go (Todas las versiones anteriores a V13.2), Teamcenter Visualization (Todas las versiones anteriores a V13.2). La biblioteca Jt981.dll de las aplicaciones afectadas carece de una comprobación apropiada de los datos suministrados por el usuario antes de llevar a cabo otras operaciones libres en un objeto cuando se analizan los archivos JT. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. (ZDI-CAN-13430)
