    Synopsis
    ========

    A vulnerability in the Speedtouch USB driver can be exploited to allow
    local users to execute arbitrary code with escalated privileges.

    Background
    ==========

    The speedtouch package contains a driver for the ADSL SpeedTouch USB
    modem.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-dialup/speedtouch < 1.3.1 >= 1.3.1

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

    The Speedtouch USB driver contains multiple format string
    vulnerabilities in modem_run, pppoa2 and pppoa3. This flaw is due to an
    improperly made syslog() system call.

    Impact
    ======

    A malicious local user could exploit this vulnerability by causing a
    buffer overflow, and potentially allowing the execution of arbitrary
    code with escalated privileges.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Speedtouch USB driver users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-dialup/speedtouch-1.3.1"
