Description

In Xpdf prior to 4.04, the DCT (JPEG) decoder was incorrectly allowing the 'interleaved' flag to be changed after the first scan of the image, leading to an unknown integer-related vulnerability in Stream.cc.

• 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.
