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"
