Description

FFmpeg n6.1.1 is Integer Overflow. The vulnerability exists in the parse_options function of sbgdec.c within the libavformat module. When parsing certain options, the software does not adequately validate the input. This allows for negative duration values to be accepted without proper bounds checking.

• 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.
