Integer overflow in the quicktime_read_pascal function in libquicktime 1.2.4 and earlier allows remote attackers to cause a denial of service or possibly have other unspecified impact via a crafted hdlr MP4 atom.
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.
