Lynx is a text-mode browser for the World Wide Web. It supports
|
|
multiple URL types, including HTTP and NNTP URLs.

<p>
|
|
When accessing a NNTP URL, Lynx connects to a NNTP server and
|
|
retrieves information about the available articles in the target
|
|
newsgroup. Ulf Harnhammar discovered a buffer overflow in a function
|
|
that handles the escaping of special characters.

<impact type="normal">
|
|
<p>
|
|
An attacker could setup a malicious NNTP server and entice a user
|
|
to access it using Lynx (either by creating NNTP links on a web page or
|
|
by forcing a redirect for Lynx users). The data returned by the NNTP
|
|
server would trigger the buffer overflow and execute arbitrary code
|
|
with the rights of the user running Lynx.
|
|

</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-2.8.5-r1"</code>
