An uninitialized memory access vulnerability exists in the way Aspose.PDF 19.2 for C++ handles invalid parent object pointers. A specially crafted PDF can cause a read and write from uninitialized memory, resulting in memory corruption and possibly arbitrary code execution. To trigger this vulnerability, a specifically crafted PDF document needs to be processed by the target application.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
The product uses or accesses a resource that has not been initialized.
