Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. An out-of-bounds read
was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds read is
triggered when Exiv2 is used to read the metadata of a crafted image file.
An attacker could potentially exploit the vulnerability to cause a denial
of service, if they can trick the victim into running Exiv2 on a crafted
image file. The bug is fixed in version v0.27.5.
