There is an invalid free in MiniPS::delete0 in minips.cpp that leads to a Segmentation fault in sam2p 0.49.4. A crafted input will lead to a denial of service or possibly unspecified other impact.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
