Synopsis
========
A vulnerability has been discovered in ELinks allowing for the
user-assisted execution of arbitrary code.
Background
==========
ELinks is a text-mode web browser.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-client/elinks < 0.11.2-r1 >= 0.11.2-r1
Description
===========
Arnaud Giersch discovered that the "add_filename_to_string()" function
in file intl/gettext/loadmsgcat.c uses an untrusted relative path,
allowing for a format string attack with a malicious .po file.
Impact
======
A local attacker could entice a user to run ELinks in a specially
crafted directory environment containing a malicious ".po" file,
possibly resulting in the execution of arbitrary code with the
privileges of the user running ELinks.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All ELinks users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/elinks-0.11.2-r1"
