Description

FFmpeg n6.1.1 has a vulnerability in the AVI demuxer of the libavformat library which allows for an integer overflow, potentially resulting in a denial-of-service (DoS) condition.

• CWE-190Integer Overflow or WraparoundThe 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.
