The BASS Audio Library 2.4.14 under Windows is prone to a BASS_StreamCreateFile Use after Free vulnerability via a crafted .ogg file. An attacker can exploit this to gain access to sensitive information that may aid in further attacks. A failure in exploitation leads to denial of service.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
