1) problem description, brief discussion, solution, upgrade information
IMP is a well known PHP-based web-mail system.
Some SQL-injection vulnerabilities were found in IMP 2.x that
allow an attacker to access the underlying database. No authentication
is needed to exploit this bug.
An attacker can gain access to protected information or, in conjunction
with PostgreSQL, execute shell commands remotely.
There is no temporary fix known. Please install the new packages from
our FTP servers.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- mod_php4
A buffer overflow in the wordwrap() function has been reported.
New packages will be prepared and should be available on our ftp
servers soon.
- libmcrypt
Several buffer overflows in libmcrypt were discovered by Ilia
Alshanetsky. The buffer overflows can lead to system compromise.
New packages are currently being build.
- vim
Georgi Guninski <guninski@guninski.com> reported a security problem
with vim's modeline support that allows the execution of commands
when a malformed file was opened. This bug may even be exploited
through MUAs like mutt.
We recommend to turn off this feature globally by adding the line:
set modelines=0
to the global configuration file /etc/vimrc. All currently supported
SuSE products are affected by this problem.
Modeline support is disabled by default in future version of SuSE
Linux.
- openldap2
The BER decoding routines of the openldap2 packages for
SL 8.1 and SLES8 contained a bug which allowed remote attackers to mount a DoS attack against vulnerable OpenLDAP servers. It is
necessary to update the openldap2-devel, openldap2-client and
openldap2 packages in order to prevent such attack.
New packages will be available on our FTP servers soon.
- mpg123
Our update directories on our ftp server for the SuSE Linux
distributions 7.3, 8.0 and 8.1 contain update packages for the mpg123
package. These updates fix a security problem with mpg123 that can
result in the execution of arbitrary commands upon playing a specially
crafted mpeg audio layer 3 file. Other versions of SuSE Linux than
mentioned above do not contain a vulnerable version of the mpg123 mp3
player.
- pam_xauth
SuSE Linux starting with version 7.2 contain a PAM (Pluggable
Authentication Module) called pam_xauth which can be used to pass on
X11-authentification data (cookies, see "man Xsecurity") if a user
uses /bin/su to assume the privileges of another user. Since the
possession of the X11 authentification cookie grants access to the
running X-server and all of its resources, this should be considered a
security problem if the feature cannot be turned off by a non-root
user. The presence of the pam_xauth PAM does not represent a threat
such if it is not enabled by default.
By default, the pam_xauth module is not enabled in all SuSE products.
We recommend to use the /usr/X11R6/bin/sux wrapper script for the
su command that comes with SuSE products to pass on X11
authentification data if so desired intentionally by the user.
- syslinux
The syslinux bootloader has been found vulnerable to a not closely
named security weakness by Dan Hollis if the bootloader program is
installed setuid root.
We do not believe that elevated privileges are beneficial for a
bootloader. The packages in SuSE Linux are not vulnerable to the
weakness.

3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SuSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum
