Synopsis
========

gprostats, distributed with GProFTPD, is vulnerable to a format string
vulnerability, potentially leading to the execution of arbitrary code.

Background
==========

GProFTPD is a GTK+ administration tool for the ProFTPD server. GProFTPD
is distributed with gprostats, a utility to parse ProFTPD transfer
logs.

Affected packages
=================

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected
    -------------------------------------------------------------------
  1  net-ftp/gproftpd       < 8.1.9                           >= 8.1.9

Description
===========

Tavis Ormandy of the Gentoo Linux Security Audit Team has identified a
format string vulnerability in the gprostats utility.

Impact
======

An attacker could exploit the vulnerability by performing a specially
crafted FTP transfer, the resulting ProFTPD transfer log could
potentially trigger the execution of arbitrary code when parsed by
GProFTPD.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All GProFTPD users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-ftp/gproftpd-8.1.9"
