Use-After-Free, Out-of-bounds Write and Heap-based Buffer Overflow vulnerabilities exist in the DWG and DXF file reading procedure in SOLIDWORKS Desktop from Release SOLIDWORKS 2021 through Release SOLIDWORKS 2023. These vulnerabilities could allow an attacker to execute arbitrary code while opening a specially crafted DWG or DXF file.
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 reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
