SuSE Security Announcement
Package: samba 2.0.5 (and previous versions)
Date: Tue Aug 17 07:03:33 CEST 1999
Affected: all Linux systems using samba <= 2.0.5
______________________________________________________________________________
Some security holes were discovered in the package mentioned above.
Please update as soon as possible or disable the service if you are using
this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected as
well, please contact your vendor for information about this issue.
Please note, that that we provide this information on as "as-is" basis only.
There is no warranty whatsoever and no liability for any direct, indirect or
incidental damage arising from this information or the installation of
the update package.
______________________________________________________________________________
1. Problem Description
a) A setuid root installed smbmnt could lead to a security breach due to
a race condition.
b) The NetBIOS name server nmbd is vulnerable to a denial-of-service attack.
c) The message service of the SMB-/CIFS-server has got a buffer overflow.
2. Impact
a) Users could mount arbitrary points in the filesystem, if smbmnt is
setuid root. (smbmnt isn't installed setuid by default)
b) If the DoS attack was triggered, the nmbd daemon uses up CPU resources.
c) The buffer overflow is only exploitable, if the "message command"
option is set in the smb.conf file. (these option isn't set by default)
3. Solution
Install the updated package, which is available from our
ftp server sine some weeks.
