Title: ELinks: User-assisted execution of arbitrary code (GLSA 200706-03)
Date: June 06, 2007
A vulnerability has been discovered in ELinks allowing for the user-assisted execution of arbitrary code.
ELinks is a text-mode web browser.
Vulnerable: < 0.11.2-r1
Unaffected: >= 0.11.2-r1
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All ELinks users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=www-client/elinks-0.11.2-r1"
