|
|
Niels Heinen has discovered a buffer overflow in the socket_getline()
|
|
function of Newspost, which can be triggered by providing long strings
|
|
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 ">=net-nntp/newspost-2.0-r1"</code>
|
|
</resolution>
