GLSA-200407-05 : XFree86, X.org: XDM ignores requestPort setting

high Nessus Plugin ID 14538

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200407-05 (XFree86, X.org: XDM ignores requestPort setting)

 XDM will open TCP sockets for its chooser, even if the DisplayManager.requestPort setting is set to 0. Remote clients can use this port to connect to XDM and request a login window, thus allowing access to the system.
 Impact :

 Authorized users may be able to login remotely to a machine running XDM, even if this option is disabled in XDM's configuration. Please note that an attacker must have a preexisting account on the machine in order to exploit this vulnerability.
 Workaround :

 There is no known workaround at this time. All users should upgrade to the latest available version of X.

Solution

If you are using XFree86, you should run the following:
 # emerge sync # emerge -pv '>=x11-base/xfree-4.3.0-r6' # emerge '>=x11-base/xfree-4.3.0-r6' If you are using X.org's X11 server, you should run the following:
 # emerge sync # emerge -pv '>=x11-base/xorg-x11-6.7.0-r1' # emerge '>=x11-base/xorg-x11-6.7.0-r1'
