CVE-2021-29473 log

Source
Severity Low
Remote No
Type Denial of service
Description
An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. 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. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as `insert`.

The bug is fixed in version v0.27.4.
