1) problem description, brief discussion, solution, upgrade information
The webalizer is a widely used tool for analyzing web server logs and
produce statistics in HTML format.
An exploitable bug was found in webalizer which allows a remote attacker
to execute commands on other client machines or revealing sensitive
information by placing HTML tags in the right place. This is possible
due to missing sanity checks on untrusted data - hostnames and search
keywords in this case - that are received by webalizer. This kind of attack
is also known as "Cross-Site Scripting Vulnerability".
Additionally the untrusted data will be written to files on the server
running webalizer; this may lead to further problems when using this
data as input for third-party software/scripts.
There is no known temporary fix, so please update your system with
the new RPMs from our FTP server.
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.
- nvi
Takeshi Uno found a format tag vulnerability in all versions of nvi.
The bug will be fixed in future version of SuSE Linux.
- Please watch out for more announcements that are currently in our queue.
