medium Nessus Plugin ID 72129

Language:

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.
