Exiv2 is a C++ library and a command-line utility to read, write, delete
and modify Exif, IPTC, XMP and ICC image metadata. An out-of-bounds read
was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a command-line
utility and C++ library for reading, writing, deleting, and modifying the
metadata of image files. The out-of-bounds read is triggered when Exiv2 is
used to write metadata into a crafted image file. An attacker could
potentially exploit the vulnerability to cause a denial of service by
crashing Exiv2, if they can trick the victim into running Exiv2 on a
crafted image file. Note that this bug is only triggered when writing the
metadata, which is a less frequently used Exiv2 operation than reading the
metadata. For example, to trigger the bug in the Exiv2 command-line
application, you need to add an extra command-line argument such as
insert. The bug is fixed in version v0.27.4. Please see our security
policy for information about Exiv2 security.
