Severity:	normal
Title:	LinPopUp: Buffer overflow in message reply
Date:	01/04/2005
Bugs:	#74705
ID:	200501-01

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	Architecture(s)
net-im/linpopup	< 2.0.4-r1	>= 2.0.4-r1	All supported architectures

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"
