Name of the Vulnerable Software and Affected Versions Exiv2 version 0.27-RC3

Description The issue is related to a buffer overflow in the tiffimage int.cpp component of the Exiv2 library, which can lead to a remote denial of service attack when a crafted input is processed. This can cause a SEGV in Exiv2::Internal::TiffParserWorker::findPrimaryGroups.
