Synopsis
=======
A vulnerability in GNU TeXmacs could result in privilege escalation.

Background
=========
GNU TeXmacs is a free WYSIWYG editing platform with special features
for scientists.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-office/texmacs         < 1.0.7.2-r1            >= 1.0.7.2-r1

Description
==========
The texmacs and tm_mupad_help scripts in TeXmacs place a zero-length
directory name in the LD_LIBRARY_PATH, which might result in the
current working directory (.) to be included when searching for
dynamically linked libraries.

Impact
=====
A local attacker could gain escalated privileges via a specially
crafted shared library.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All GNU TeXmacs users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-office/texmacs-1.0.7.2-r1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since April 02, 2011. It is likely that your system is
already no longer affected by this issue.
