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 .
The vulnerability could not be verified in older SuSE
distributions.
