<description>
<p>A vulnerability has been discovered in usbview. Please review the CVE identifier referenced below for details.</p>
</description>
<impact type="high">
<p>USBView allows some local users (e.g., ones logged in via SSH) to execute arbitrary code as root because certain Polkit settings (e.g., allow_any=yes) for pkexec disable the authentication requirement. Code execution can, for example, use the --gtk-module option.</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All USBView users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/usbview-2.2"
</code>
</resolution>
