Description

An exploitable use-after-free vulnerability exists in the way LZW-compressed streams are processed in Aspose.PDF 19.2 for C++. A specially crafted PDF can cause a dangling heap pointer, resulting in a use-after-free condition. To trigger this vulnerability, a specifically crafted PDF document needs to be processed by the target application.

• CWE-416Use After FreeThe 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
