Synopsis
=======
A buffer overflow can be exploited to crash Newspost remotely and
potentially execute arbitrary code.

Background
=========
Newspost is a Usenet News binary autoposter.

Affected packages
================
    -------------------------------------------------------------------
     Package            /  Vulnerable  /                    Unaffected
    -------------------------------------------------------------------
  1  net-nntp/newspost      < 2.0-r1                         >= 2.0-r1

Description
==========
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
=====
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.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Newspost users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-nttp/newspost-2.0-r1"
