arbitrary code.

Background
==========
Vinagre is a VNC Client for the GNOME Desktop.

Affected packages
=================
-------------------------------------------------------------------

Description
===========
Alfredo Ortega (Core Security Technologies) reported a format string
error in the vinagre_utils_show_error() function in
src/vinagre-utils.c.

Impact

the remote execution of arbitrary code with the privileges of the user
running the application.

Workaround

All Vinagre users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/vinagre-0.5.2"
