Description

An issue in mp4v2 2.0.0 allows an attacker to execute arbitrary code via the MP4RtpAtom::ReadHntiType() in src/atom_rtp.cpp. A specially crafted MP4 file can cause an undersized rtp atom to produce a near-2^64 allocation size through an unchecked offset subtraction

CWE-190

Integer Overflow or Wraparound

The product 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 occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
