1) problem description, brief discussion, solution, upgrade information
UUCP is a well known tool suite for copying data between unix-like
systems. Zen-Parse reported that the higher privileges of uux (UID
uucp) aren't dropped if long options instead of normal (short) options
are used. An attacker could exploit this hole, by specifying a malicious
configuration file to execute and/or access arbitrary data with the
privilege of user uucp.
As a temporary fix, you could either uninstall uucp from your system,
if not needed:
- rpm -e uucp
or remove the set[ug]id bit
- chmod ug-s /usr/bin/uux
Please, don't forget to add the permissions settings accordingly to
your /etc/permissions.local file.
Download the update package from locations described below and install
the package with the command `rpm -Uhv file.rpm'. The md5sum for each
file is in the line below. You can verify the integrity of the rpm
files using the command
`rpm --checksig --nogpg file.rpm',
independently from the md5 signatures below.

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 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.
