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"
