Base vector

AV:N/AC:M/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Exiv2 versions v0.27.3 and earlier

Description The issue is related to an out-of-bounds read in the Exiv2 library, which can be triggered when writing metadata into a crafted image file. This could potentially allow a remote attacker to cause a denial of service by crashing Exiv2 if they can trick the victim into running Exiv2 on a crafted image file. The bug is less frequently triggered since it occurs during metadata writing, a less common operation than reading metadata.

Recommendations For Exiv2 versions v0.27.3 and earlier, update to version v0.27.4 to resolve the issue. As a temporary workaround, consider avoiding the use of the metadata writing functionality in Exiv2 until the update is applied.
