[slackware-security]  Samba buffer overflow fixed

The samba packages in Slackware 8.1 and -current have been patched to fix
a security problem.  All sites running samba should upgrade.


Here are the details from the Slackware 8.1 ChangeLog:
+--------------------------+
Sat Mar 15 13:49:04 PST 2003
patches/packages/samba-2.2.8-i386-1.tgz:  Upgraded to Samba 2.2.8.

  From the Samba web site:

     * (14th Mar, 2003) Security Release - Samba 2.2.8

     A flaw has been detected in the Samba main smbd code which
     could allow an external attacker to remotely and anonymously
     gain Super User (root) privileges on a server running a
     Samba server. This flaw exists in previous versions of Samba
     from 2.0.x to 2.2.7a inclusive. This is a serious problem
     and all sites should either upgrade to Samba 2.2.8
     immediately or prohibit access to TCP ports 139 and 445.

(* Security fix *)

More information may be found in the Samba release notes.
