Integer Overflow or Wraparound
Integer overflow in the 'asf_write_packet' function in 'libavformat/asfenc.c' in FFmpeg before 2.4.13, 2.5.x before 2.5.10, 2.6.x before 2.6.7, 2.7.x before 2.7.5 and 2.8.x before 2.8.5, allows remote attackers to cause a Denial of Service or possibly have unspecified other impact via a crafted PTS (aka presentation timestamp) value in a '.mov' file.
CWE-190 - Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control.
