Description

Background

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

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"
