|Package||www-client/lynx on all architectures|
|Affected versions||< 2.8.5-r2|
|Unaffected versions||>= 2.8.5-r2|
Lynx is a fully-featured WWW client for users running cursor-addressable, character-cell display devices such as vt100 terminals and terminal emulators.
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.
A remote attacker can entice a user to access a malicious HTTP server, causing Lynx to execute arbitrary commands.
Disable "lynxcgi" links by specifying the following directive in lynx.cfg:
All Lynx users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-client/lynx-2.8.5-r2"
