CVE-2021-32617 log

Source
Severity Low
Remote Yes
Type Denial of service
Description
An inefficient algorithm (quadratic complexity) was found in Exiv2 before version 0.27.4. The inefficient algorithm 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, 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. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as rm.
