Name of the Vulnerable Software and Affected Versions Exiv2 version 0.26

Description The issue is related to a denial of service caused by an integer overflow, which can lead to a heap-based buffer over-read. This occurs when the Exiv2::IptcParser::decode function in iptc.cpp, called from psdimage.cpp in the PSD image reader, processes a crafted PSD image file.

Recommendations For Exiv2 version 0.26, consider avoiding the use of crafted PSD image files until a patch is available. As a temporary workaround, restrict the processing of PSD files to minimize the risk of exploitation.
