Hi,

The following vulnerability was published for exiv2.

CVE-2021-32815[0]:
| Exiv2 is a command-line utility and C++ library for reading, writing,
| deleting, and modifying the metadata of image files. The assertion
| failure is triggered when Exiv2 is used to modify 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 modifying 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 `fi`. ### Patches
| The bug is fixed in version v0.27.5. ### References Regression test
| and bug fix: #1739 ### For more information Please see our [security
| policy](https://github.com/Exiv2/exiv2/security/policy) for
| information about Exiv2 security.
