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 when parsing JT 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-13419)
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 no comprueba apropiadamente los datos proporcionados por el usuario cuando se analizan los archivos JT. Esto podría resultar en una escritura fuera de límites más allá del final de una estructura asignada. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. (ZDI-CAN-13419)
