Debian DSA-2661-1 : xorg-server - information disclosure

low Nessus Plugin ID 66004

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

David Airlie and Peter Hutterer of Red Hat discovered that xorg-server, the X.Org X server was vulnerable to an information disclosure flaw related to input handling and devices hotplug.

When an X server is running but not on front (for example because of a VT switch), a newly plugged input device would still be recognized and handled by the X server, which would actually transmit input events to its clients on the background.

This could allow an attacker to recover some input events not intended for the X clients, including sensitive information.

Solution

Upgrade the xorg-server packages.

For the stable distribution (squeeze), this problem has been fixed in version 2:1.7.7-16.
