CVE-2021-37616

Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. A null pointer
dereference was found in Exiv2 versions v0.27.4 and earlier. The null
pointer dereference is triggered when Exiv2 is used to print 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. Note that this bug is only
triggered when printing the interpreted (translated) data, which is a less
frequently used Exiv2 operation that requires an extra command line option
(-p t or -P t). The bug is fixed in version v0.27.5.
