A Use After Free vulnerability affecting the PAR file reading procedure in SOLIDWORKS eDrawings on Release SOLIDWORKS Desktop 2025 could allow an attacker to execute arbitrary code while opening a specially crafted PAR file.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
