Synopsis
========

Multiple vulnerabilities have been discovered in libXpm, which is
included in LessTif, that can potentially lead to remote code
execution.

Background
==========

LessTif is a clone of OSF/Motif, which is a standard user interface
toolkit available on Unix and Linux.

Affected packages
=================

    -------------------------------------------------------------------
     Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
  1 x11-libs/lesstif < 0.94.0 >= 0.94.0

Description
===========

Multiple vulnerabilities, including buffer overflows, out of bounds
memory access and directory traversals, have been discovered in libXpm,
which is shipped as a part of the X Window System. LessTif, an
application that includes libXpm, suffers from the same issues.

Impact
======

A carefully-crafted XPM file could crash applications making use of the
LessTif toolkit, potentially allowing the execution of arbitrary code
with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All LessTif users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/lesstif-0.94.0"
