Lynx is a fully-featured WWW client for users running
|
|
cursor-addressable, character-cell display devices such as vt100
|
|
terminals and terminal emulators.

<p>
|
|
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 type="normal">
|
|
<p>
|
|
A remote attacker can entice a user to access a malicious HTTP
|
|
server, causing Lynx to execute arbitrary commands.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable "lynxcgi" links by specifying the following directive in
|
|
lynx.cfg:
|
|
</p>
|
|
<code>
|
|
TRUSTED_LYNXCGI:none</code>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Lynx users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-client/lynx-2.8.5-r2"</code>
|
|
</resolution>
