    Synopsis
    ========

    A vulnerability has been discovered in usbview where certain users can
    trigger a privilege escalation.

    Background
    ==========

    USBView is a tool to display the topology of devices on the USB bus.

    Affected packages
    =================

    Package Vulnerable Unaffected
    ----------------- ------------ ------------
    app-admin/usbview < 2.2 >= 2.2

    Description
    ===========

    A vulnerability has been discovered in usbview. Please review the CVE identifier referenced below for details.

    Impact
    ======

    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.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All USBView users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-admin/usbview-2.2"

    References
