-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ 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. ______________________________________________________________________________ Here is the md5 checksum of the fixed package, please verify these before installing the new package: 7cef0cbfcc8ca05b9cb96159bae80e6a samba.rpm b2c1f3cf4562f98dbe3b2074e8c66ded samba-2.0.5a-3.src.rpm ______________________________________________________________________________ You will find the update on our ftp-Server: ftp.suse.com/pub/suse/i386/update/6.1/n1/samba.rpm (i386, glibc) ftp.suse.com/pub/suse/i386/update/6.1/n1/samba-2.0.5a-0.src.rpm Webpage for patches: http://www.suse.de/patches/index.html or try the following web pages for a list of mirrors: http://www.suse.de/ftp.html http://www.suse.com/ftp_new.html ______________________________________________________________________________ SuSE has got two free security mailing list services to which any interested party may subscribe: suse-security@suse.com - unmoderated and for general/linux/SuSE security discussions.
