Mandrake: tcl/tk vulnerability Print E-mail

Mandrake Some problems were discovered with the Tcl/Tk development environment. The expect application would search for its libraries in /var/tmp prior to searching in other directories, which could allow a local user to gain root privilege by writing a trojan library and waiting for the root user to run the mkpasswd utility.

                Mandrake Linux Security Update Advisory
________________________________________________________________________

Package name:           tcl/tk
Advisory ID:            MDKSA-2002:060
Date:                   September 23rd, 2002
Affected versions:      7.2, 8.0, 8.1, 8.2, Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

 Some problems were discovered with the Tcl/Tk development environment.
 The expect application would search for its libraries in /var/tmp prior
 to searching in other directories, which could allow a local user to
 gain root privilege by writing a trojan library and waiting for the
 root user to run the mkpasswd utility.  This is fixed in version 5.32
 of expect.  A similiar vulnerability has been fixed in the tcltk
 package which searched for its libraries in the current working
 directory prior to searching in other directories.  This could be
 used to execute arbitrary code by local users through the use of
 a trojan library.
