Subject       : CA-99-05 Vulnerability in statd and automountd
                                                            Date   :  11-Jun-99
===============================================================================

By courtesy of CERT Coordination Center we received the following information.

CERT Coordination Center advisory CA-99-05 reports two vulnerabilities that
are being used together by intruders to gain access to vulnerable systems.
The first vulnerability is in rpc.statd, a program used to communicate state
changes among NFS clients and servers. The second vulnerability is in
automountd, a program used to automatically mount certain types of file
systems.

This combination of vulnerabilities potentionally allows a remote intruder
to execute arbitrary commands with the administrative privileges of the
automountd service, typically root.

This advisory provides information about which systems are vulnerable
(typically systems running older versions of rpc.statd and automountd) and
provides pointers to patches from various vendors. Note that both
vulnerabilities are already known for a while. CERT Coordination Center has
received many reports about these vulnerabilities being exploited and has
released this advisory to call attention to these problems so that system
and network administrators who have not addressed these problems do so
immediately.

CERT-NL recommends to check whether your systems are vulnerable and to apply
the necessary patches were applicable.

All CERT Coordination Center advisories are mirrored by CERT-NL.
