A maliciously crafted 3DM file when parsed in AcTranslators.exe through Autodesk AutoCAD can force a Heap-Based Buffer Overflow vulnerability. A malicious actor can leverage this vulnerability to cause a crash, write sensitive data, or execute arbitrary code in the context of the current process.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
