http://security.gentoo.org/

Severity:	normal
Title:	Newspost: Buffer overflow vulnerability
Date:	02/03/2005
Bugs:	#78530
ID:	200502-05

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	Architecture(s)
net-nntp/newspost	< 2.1.1-r1	>= 2.0-r1	All supported architectures

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-nntp/newspost-2.0-r1"
