Clint Ruoho reported that the fix for CVE-2005-2929 (GLSA 200511-09)
|
|
only disabled the lynxcgi:// handler when not using the advanced mode.
|

|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker can entice a user to access a malicious HTTP server,
|
|
causing Lynx to execute arbitrary commands. NOTE: The advanced mode is
|
|
not enabled by default. Successful exploitation requires the
|
|
"lynxcgi://" protocol to be registered with lynx on the victim's
|
|
system.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Lynx users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-client/lynx-2.8.6-r4"</code>
