An issue was discovered in Bento4 through v1.6.0-637. A NULL pointer dereference exists in the function AP4_StszAtom::GetSampleSize() located in Ap4StszAtom.cpp. It allows an attacker to cause Denial of Service.
The AP4_Processor::Process function in Core/Ap4Processor.cpp in Bento4 mp4encrypt before 1.5.0-616 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted mp4 file.
