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"
