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::IptcData::printStructure function, specifically in the "!= 0x1c" case. This can be exploited by remote attackers to cause a denial of service using a crafted TIFF file.

Recommendations For Exiv2 version 0.26, consider avoiding the use of crafted TIFF files until a patch is available. As a temporary workaround, restrict the processing of TIFF files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
