DescriptionNVD

A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The BMP_Loader.dll library in affected applications lacks proper validation of user-supplied data prior to performing further free operations on an object when parsing BMP files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13196)
