Live555 before 2019.08.16 has a Use-After-Free because GenericMediaServer::createNewClientSessionWithId can generate the same client session ID in succession, which is mishandled by the MPEG1or2 and Matroska file demultiplexors.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
