The update packages fix a security problem related to the recently discovered problems with source ip based access restrictions in a user's ~/.ssh/authorized_keys2 file. The packages will appear shortly on our ftp servers. Please note that packages for the distributions 6.3 and up including 7.0 containing cryptographic software are located on the German ftp server ftp.suse.de, all other packages can be found on ftp.suse.com at the usual location. We will issue a dedicated Security announcement for the openssh package. - The ziptool program runs setuid root in the easy permission mode and contains an overflow which allows local attackers to gain root privileges. A zipdrive must be configured and a zipdisk being inserted in order to exploit the bug. The overflow has been fixed. Please update your packages. - The ncpfs package containing the setuid root programs ncpmount and ncpumount was vulnerable to local bufferoverflow attacks. The package has been fixed. ______________________________________________________________________________ 3) standard appendix: SuSE runs two security mailing lists to which any interested party may subscribe: email@example.com - general/linux/SuSE security discussion.
