GLSA-201401-27 : GNU TeXmacs: Privilege escalation

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201401-27
(GNU TeXmacs: Privilege escalation)

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.

Solution :

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.
