SUSE SLES12 Security Update : exiv2 (SUSE-SU-2022:3543-1)

medium Nessus Plugin ID 165744

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3543-1 advisory.

- Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An inefficient algorithm (quadratic complexity) was found in Exiv2 versions v0.27.3 and earlier. 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. The bug is fixed in version v0.27.4. 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`. (CVE-2021-32617)

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

Solution

Update the affected libexiv2-12 and / or libexiv2-devel packages.
