Integer overflow bug in function minitiff_read_info() of optipng 0.7.6 allows an attacker to remotely execute code or cause denial of service.
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.
