______________________________________________________________________________
1) problem description, brief discussion, solution, upgrade
information
GNU cfengine is an abstract programming language for system
administrators of large heterogeneous networks, used for
maintenance and administration. Pekka Savola <pekkas@netcore.fi>
has found several format string vulnerabilities in syslog() calls
that can be abused to either make the cfengine program to
segfault and die or to execute arbitrary commands as the user the
cfengine process runs as (usually root).
The cfengine package is not installed per default, and not
activated when installed. Thus, the vulnerability affects only
systems where the administrator actively uses this tool.
The only efficient fix for the problem is an update of the
cfengine package since access restrictions limit the attack
possibilities to a closed group of hosts/users only.
Download the update package from locations desribed below and install
the package with the command `rpm -Fhv 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:
- gnorpm
A race condition has been found in the gnorpm program, a GUI
for the rpm system. The issue will be addressed in a
following advisory.
- ncurses
The ncurses library contains buffer overflows that are
exploitable when user-supplied terminfo databases are
processed. This imposes a security risk on programs/binaries
that are linked against libncurses and run with special
privileges. Both workaround and clean solution is to remove
the suid bit from all executable files with setuid bit set.
The issue will be addressed in a following security
announcement.
- apache mod_rewrite, php
A bug has been discovered in the apache package that allows
attackers to read arbitrary files on a system that runs
apache. The responsible apache module named "mod_rewrite" is
not used by default on SuSE installations of the apache
package. The issue will be addressed in a following security
announcement.
- usermode/userhelper
userhelper is a suid helper program designed to let the user
who is logged on to the console execute some programs with
root privileges. SuSE distributions do not contain the
usermode package and therefore are not vulnerable to the
security problems recently discovered in the usermode package.
- tmpwatch
The tmpwatch packages as shipped with SuSE distributions are
not vulnerable to the attacks as discussed on security forums
because we ship an older version that does not provide the
functionality that can be exploited.
- lprNG
The versions of the lprNG package that come with SuSE
distributions are not vulnerable to the format string parsing
errors as discussed in security forums.
- traceroute
The traceroute program has been found vulnerable to a bug
(`traceroute -g 1 -g 1') in many distributions. Newer SuSE
distributions have a different implementation of the
traceroute program and are not vulnerable to the bug found by
Pekka Savola <pekkas@netcore.fi>. The vulnerability could not
be verified in older SuSE distributions.
