Severity: Normal Title: Lynx: Arbitrary command execution Date: November 13, 2005 Bugs: #112213 ID: 200511-09

Synopsis ========
Lynx is vulnerable to an issue which allows the remote execution of arbitrary commands.
Background ==========
Lynx is a fully-featured WWW client for users running cursor-addressable, character-cell display devices such as vt100 terminals and terminal emulators.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/lynx < 2.8.5-r2 >= 2.8.5-r2
Description ===========
iDefense labs discovered a problem within the feature to execute local cgi-bin programs via the "lynxcgi:" URI handler. Due to a configuration error, the default settings allow websites to specify commands to run as the user running Lynx.
Impact ======
A remote attacker can entice a user to access a malicious HTTP server, causing Lynx to execute arbitrary commands.
Workaround ==========
Disable "lynxcgi" links by specifying the following directive in lynx.cfg:
TRUSTED_LYNXCGI:none
Resolution ==========
All Lynx users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/lynx-2.8.5-r2"
