Synopsis
=======
LinPopUp contains a buffer overflow potentially allowing execution of
arbitrary code.

Background
=========
LinPopUp is a graphical application that acts as a frontend to Samba
client messaging functions, allowing a Linux desktop to communicate
with a Microsoft Windows computer that runs Winpopup.

Affected packages
================
    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  net-im/linpopup     < 2.0.4-r1                        >= 2.0.4-r1

Description
==========
Stephen Dranger discovered that LinPopUp contains a buffer overflow in
string.c, triggered when replying to a remote user message.

Impact
=====
A remote attacker could craft a malicious message that, when replied
using LinPopUp, would exploit the buffer overflow. This would result in
the execution of arbitrary code with the privileges of the user running
LinPopUp.

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

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-im/linpopup-2.0.4-r1"
