librtmp (RTMPDump) through 2.6 contains a heap out-of-bounds read vulnerability in AMFProp_Decode that reads an AMF0 strict-array element count before checking that four bytes remain. A malicious RTMP server or man in the middle can send an AMF0 body ending with a strict-array type byte and fewer than four trailing bytes to crash the client.
