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"
