Niels Heinen has discovered a buffer overflow in the socket_getline()

that do not end with a newline character.

<impact type="normal">
<p>
A remote attacker could setup a malicious NNTP server and entice a
Newspost user to post to it, leading to the crash of the Newspost
process and potentially the execution of arbitrary code with the rights
of the Newspost user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Newspost users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-nntp/newspost-2.0-r1"</code>
