Lynx is a text-mode browser for the World Wide Web. It supports
multiple URL types, including HTTP and NNTP URLs.
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">
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.
There is no known workaround at this time.
All Lynx users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-client/lynx-2.8.5-r1&quot;</code>
