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.
