Hi,

The following vulnerability was published for exiv2.

CVE-2021-34335[0]:
| Exiv2 is a command-line utility and C++ library for reading, writing,
| deleting, and modifying the metadata of image files. A floating point
| exception (FPE) due to an integer divide by zero was found in Exiv2
| versions v0.27.4 and earlier. The FPE 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.


If you fix the vulnerability please also make sure to include the
