                     ESB-98.176 -- Red Hat Linux Bulletin
                    SECURITY: new samba packages available

                               17 November 1998

===========================================================================

Red Hat Software, Inc. has released the following advisory concerning a
vulnerability in installation persmissions in the samba package as
distributed in Red Hat Linux 5.2.

- ---------------------------BEGIN INCLUDED TEXT--------------------

- -----BEGIN PGP SIGNED MESSAGE-----

The Samba team brought to our attention a security vulnerability in the
samba-1.9.18p10-3 RPMs as distributed in RedHat 5.2. We would like to thank
Andrew Tridgell and the Samba team for discovering this problem.

The problem is the installation permissions of the wsmbconf binary. The RPM
installs wsmbconf as a setgid binary owned by group root and executable by
all users. Only users of Red Hat Linux 5.2 are affected.

All systems on which the RedHat 5.2 Samba RPM are installed should
immediately remove the file /usr/sbin/wsmbconf:
	rm -f /usr/sbin/wsmbconf
or upgrade to the new packages available from our updates site: 

Red Hat Linux 5.2:
