scientists.
</p>

<description>
<p>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 type="high">
<p>A local attacker could gain escalated privileges via a specially crafted
shared library.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>

<p>All GNU TeXmacs users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/texmacs-1.0.7.2-r1"
</code>
<p>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.
