Chunked mode is a HTTP 1.1 feature that allows a client to send data as a sequence of chunks rather than en bloc. This is useful if it doesn't know the overall length of the content at the time it starts transmitting. Previous versions of apache did not properly detect incorrectly encoded chunks, which caused a buffer overflow on the stack. On 32bit architectures, this overflow cannot be exploited to inject code into the httpd process and gain access to the machine, because the overflow will always result in a segmentation fault, and the process will terminate. On 64bit architectures, it may be possible for an attacker to a exploit the buffer overflow to execute arbitary code with the privileges of the httpd process (user wwwrun on SuSE Linux). 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 following command to apply the update: rpm --nodeps -Fvh apache*.rpm mod_ssl*.rpm If you have modified the configuration file /etc/httpd/httpd.conf, upgrading will backup this file to /etc/httpd/httpd.conf.rpmsave. If this is the case, make sure to restore this backup file. Finally, restart the web server using /usr/sbin/rcapache restart. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web. The SuSE security team wishes to thank Mark Cox for advance notification on this issue. For additional information, please refer to http://httpd.apache.org/info/security_bulletin_20020617.txt Due to heat problems, we were not able to build the update packages on all architectures. As soon as possible, we will make update packages for the remaining platforms available on our FTP site. i386 Intel Platform: SuSE-8.0

______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: - mozilla Cross-dependencies between mozilla and other packages in SuSE Linux products keep us from providing version upgrades for the mozilla packages. Fixing security bugs in our packages is usually done by adding the necessary patches to the existing version to ensure the compatibility and consistency that is expected from our products. In some cases (as with the mozilla package) the complexity of the issue does not allow to add patches any more. By consequence, security related issues in mozilla cannot be addressed. As a service to our user community, we provide packages of newer mozilla versions at ftp://ftp.suse.com/pub/projects/mozilla/. These packages have been verified to run fine; they are not located in the update directory of the distribution in question because we cannot make any claims about the compatibility with the other packages in the product. Security-aware users are encouraged to install the packages from the projects/ directory. - ghostscript RedHat released a security announcement concerning a problem in ghostscript, which could be exploited to gain privilege of the print server user. We are investigating whether SuSE Linux is affected. - kernel netfilter update we are in the process of preparing a kernel update that will include a security fix for a minor netfilter bug. - fetchmail we are in the process of releasing a security update for fetchmail that corrects a vulnerability that could be exploited by hostile mail servers. ______________________________________________________________________________ 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 after you downloaded the file from a SuSE ftp server or its mirrors. Then, compare the resulting md5sum with the one that is listed in the announcement. Since the announcement containing the checksums is cryptographically signed (usually using the key security@suse.de), the checksums show proof of the authenticity of the package. We disrecommend to subscribe to security lists which cause the email message containing the announcement to be modified so that the signature does not match after transport through the mailing list software. Downsides: You must be able to verify the authenticity of the announcement in the first place. If RPM packages are being rebuilt and a new version of a package is published on the ftp server, all md5 sums for the files are useless. 2) rpm package signatures provide an easy way to verify the authenticity of an rpm package. Use the command rpm -v --checksig to verify the signature of the package, where is the filename of the rpm package that you have downloaded. Of course, package authenticity verification can only target an uninstalled rpm package file. Prerequisites: a) gpg is installed b) The package is signed using a certain key. The public part of this key must be installed by the gpg program in the directory ~/.gnupg/ under the user's home directory who performs the signature verification (usually root). You can import the key that is used by SuSE in rpm packages for SuSE Linux by saving this announcement to a file ("announcement.txt") and running the command (do "su -" to be root): gpg --batch; gpg < announcement.txt | gpg --import SuSE Linux distributions version 7.1 and thereafter install the key "build@suse.de" upon installation or upgrade, provided that the package gpg is installed. The file containing the public key is placed at the toplevel directory of the first CD (pubring.gpg) and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de . - SuSE runs two security mailing lists to which any interested party may subscribe: suse-security@suse.com - general/linux/SuSE security discussion.
