Ubuntu 20.04 LTS / 21.04 / 21.10 : Exiv2 regression (USN-5043-2)

medium Nessus Plugin ID 156633

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 21.04 / 21.10 host has packages installed that are affected by a vulnerability as referenced in the USN-5043-2 advisory.

- Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of 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. The bug is fixed in version v0.27.5. (CVE-2021-37620)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected exiv2, libexiv2-27 and / or libexiv2-dev packages.
