Vulnerability Assessment Details

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

Vulnerability Assessment Summary
XFree86, X.org: XDM ignores requestPort setting

Detailed Explanation for this Vulnerability Assessment
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 permiting 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.
