1) problem description, brief discussion, solution, upgrade information
PHP is a well known and widely used web programming language.
If a PHP script runs in "safe mode" several restrictions are applied
to it including limits on execution of external programs.
An attacker can pass shell meta-characters or sendmail(8) command line
options via the 5th argument (introduced in version 4.0.5) of the mail()
function to execute shell commands or control the behavior of sendmail(8).
The CRLF injection vulnerabilities in fopen(), file(), header(), ...
allow an attacker to bypass ACLs or trigger cross-side scripting.
The mod_php4 package is not installed by default.
A temporary fix is not known.
Please note, that the following packages were rebuild too:
- mod_php4-core
- mod_php4-aolserver
- mod_php4-devel
- mod_php4-servlet
- mod_php4-roxen
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:
- glibc
Client applications which use res_search/res_nsreach and/or res_query()/
res_nquery() of libresolv could trigger a DNS decoding error, a SEGV or
leak information by reading beyond the end of a too small 'answer'
buffer.
The update packages are being built and tested. We will publish a security
announcement as soon as they are ready.
- ghostview/kghostview
Bufferoverflows have recently been discovered in these packages. They allow
attackers to execute arbitrary code with the privileges of the user
viewing special crafted documents created by the attacker. New packgaes will
soon be available on our ftp servers.
- fetchmail
Fetchmail contains remotely exploitable overflows in the mail header
parsing functions. In depth discussion of these problems can be found at
.
New packages will soon be available on our ftp servers.
- kdelibs
KDE's SSL implementation fails to check the trust chain in SSL
certificates. This bug allows faking valid SSL certificates.
New KDE packages will be available soon to fix this and other bugs.
- ethereal
Several potential security issues have been discovered in ethereal
0.9.4. After this package is tested succesfuly it will be relased.

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
