In SWFTools 0.9.2, the wav_convert2mono function in lib/wav.c does not properly restrict a multiplication within a malloc call, which allows remote attackers to cause a denial of service (integer overflow and NULL pointer dereference) via a crafted WAV file.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
