2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- openssh
After stabilizing the openssh package, updates for the distributions
6.4-7.2 are currently being prepared. 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 http://ftp.suse.de,
all other packages can be found on http://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.
