1) problem description, brief discussion, solution, upgrade information
Sdbsearch.cgi is Perl script which is part of the sdb package of SuSE Linux
was found vulnerable by using untrustworthy client input (HTTP_REFERER).
By exploiting this trust an attacker could force the sdbsearch.cgi script
to open a malicious keylist file which includes keywords and filenames.
By replacing the filename in the keylist file with the Perl pipe followed
by arbitrary shell commands the sdbsearch.cgi would execute these commands
when trying to open these 'filenames'.
Note, that the attacker needs local access to the machine to store the
keylist file on the server running sdbsearch.cgi. Misconfigured ftp
accounts, trojan tar balls or RPM files could also be used.
Sdbsearch.cgi on SuSE Linux 7.1 and 7.2 is not exploitable, because
Perl's taint mode is used, nevertheless the HTTP_REFERER variable is still
unfiltered and fully trusted. So, users of SuSE Linux 7.1 and 7.2 are
not in danger but should update to avoid future attacks.
Please update your machines with the new RPMs from our ftp server.

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
