(Debian Issues Fix) vbox3 Privilege State Error Lets Local Users Execute TCL Scripts With Root Privileges
SecurityTracker Alert ID:  1008652
SecurityTracker URL:  http://securitytracker.com/id/1008652
CVE Reference:   CVE-2004-0015   (Links to External Site)
Date:  Jan 8 2004
Impact:   Execution of arbitrary code via local system, Root access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 0.1.7 and prior versions
Description:   A vulnerability was reported in vbox3. A local user can gain root privileges on the target system.

In October 2003, it was reported that 'vboxgetty/voice.c' does not properly drop root privileges before running a user-controlled TCL script. A local user can reportedly execute arbitrary scripts with root privileges to gain root access on the system.

Impact:   A local user can execute scripts with root privileges.
Solution:   Debian has released a fix for the current stable distribution (woody) in version 0.1.7.1 and for the unstable distribution in version 0.1.8.

Package        : vbox3
Vulnerability  : privilege leak
Problem-Type   : local
Debian-specific: no
CVE Ids        : CAN-2004-0015

A bug was discovered in vbox3, a voice response system for isdn4linux,
whereby root privileges were not properly relinquished before
executing a user-supplied tcl script.  By exploiting this
vulnerability, a local user could gain root privileges.

For the current stable distribution (woody) this problem has been
fixed in version 0.1.7.1.

For the unstable distribution, this problem has been fixed in version 0.1.8.

We recommend that you update your vbox3 package.
