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.

A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. The heap overflow\n is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially\n exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a\n crafted image file. Note that this bug is only triggered when _writing_ the metadata, which is a less\n frequently used Exiv2 operation than _reading_ the metadata. For example, to trigger the bug in the Exiv2\n command-line application, you need to add an extra command-line argument such as `insert`. The bug is\n fixed in version v0.27.4. (CVE-2021-29457)\n\n - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata\n of image files.
