Evince 3.26.0 is affected by buffer overflow. The impact is: DOS / Possible code execution. The component is: backend/tiff/tiff-document.c. The attack vector is: Victim must open a crafted PDF file. The issue occurs because of an incorrect integer overflow protection mechanism in tiff_document_render and tiff_document_get_thumbnail.
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.
