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"
