CVE-2001-1375

Details

Updated Tcl/Tk packages for Red Hat Linux 7 and 7.1 fix two local
vulnerabilities.

[Updated 16 April 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems.

The Tcl/Tk development environment comprises a number of applications tcl,
tk, tix, tclX, expect, and itcl.

The expect application, prior to version 5.32, searched for its libraries
in /var/tmp before searching in other directories. This behavior could
allow local users to gain root privileges by writing a Trojan horse library
and getting the root user to run mkpasswd.

The tcl/tk package searched for its libraries in the current working
directory before other directories, which could allow local users to
execute arbitrary code by writing Trojan horse library that is under a
user-controlled directory.

These issues affect Red Hat Linux versions 7 and 7.1, they were fixed
in later Red Hat releases.

All users should upgrade to the errata packages which are not vulnerable to
these issues.


Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
