References
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-29473
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.
