Name of the Vulnerable Software and Affected Versions: Exiv2 version 0.26

Description: The issue is related to a heap-based buffer over-read in the Exiv2::Image::byteSwap4 function, which can be exploited by remote attackers using a crafted TIFF file. This can lead to the disclosure of memory data or cause a denial of service.
