Ubuntu 16.04 ESM / 18.04 ESM : KAuth vulnerability (USN-6035-1)

high Nessus Plugin ID 174591

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6035-1 advisory.

 - KDE KAuth before 5.55 allows the passing of parameters with arbitrary types to helpers running as root over DBus via DBusHelperProxy.cpp. Certain types can cause crashes, and trigger the decoding of arbitrary images with dynamically loaded plugins. In other words, KAuth unintentionally causes this plugin code to run as root, which increases the severity of any possible exploitation of a plugin vulnerability.
 (CVE-2019-7443)

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 packages.
