Synopsis
========
A vulnerability in pidgin-knotify might allow remote attackers to
execute arbitrary code.

Background
==========
pidgin-knotify is a Pidgin plug-in to display message notifications in
KDE.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-plugins/pidgin-knotify
<= 0.2.1 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.

Description
===========
pidgin-knotify does not properly sanitize shell metacharacters from
received messages.

Impact
======
A remote attacker could send a specially crafted instant message,
possibly resulting in execution of arbitrary code with the privileges
of the Pidgin process.

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

Resolution
==========
Gentoo has discontinued support for pidgin-knotify. We recommend that
users unmerge pidgin-knotify:

# emerge --unmerge "x11-plugins/pidgin-knotify"
