This module is included by default in the Apache package distributed with Conectiva Linux. There is a cross site cripting vulnerability[3][4][5] in the mod_ssl module. The "server name" field returned to the client was not being filtered, which could lead to cross site scripting attacks if the "UseCanonicalName" option is turned off (which is not the default) and wildcard DNS is in use. SOLUTION All apache users should upgrade their packages. IMPORTANT: it is necessary to manually restart the httpd server after upgrading the packages if it was already running. In order to do this, execute the following as root: service httpd stop (wait a few seconds and check with "ps ax|grep httpd" if there are any httpd processes running. On a busy webserver this could take a while) service httpd start REFERENCES 1. http://www.modssl.org 2. http://httpd.apache.org 3. http://www.mail-archive.com/modssl-users@modssl.org/msg15366.html 4. http://www.mail-archive.com/modssl-users@modssl.org/msg15368.html 5. http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-1157 DIRECT DOWNLOAD LINKS TO THE UPDATED PACKAGES ftp://atualizacoes.conectiva.com.br/6.0/SRPMS/apache-1.3.26-1U60_5cl.src.rpm ftp://atualizacoes.conectiva.com.br/6.0/RPMS/apache-1.3.26-1U60_5cl.i386.rpm ftp://atualizacoes.conectiva.com.br/6.0/RPMS/apache-devel-1.3.26-1U60_5cl.i386.rpm ftp://atualizacoes.conectiva.com.br/6.0/RPMS/apache-doc-1.3.26-1U60_5cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/SRPMS/apache-1.3.26-1U70_8cl.src.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/apache-1.3.26-1U70_8cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/apache-devel-1.3.26-1U70_8cl.i386.rpm ftp://atualizacoes.conectiva.com.br/7.0/RPMS/apache-doc-1.3.26-1U70_8cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/SRPMS/apache-1.3.26-1U80_5cl.src.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/apache-1.3.26-1U80_5cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/apache-devel-1.3.26-1U80_5cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/apache-doc-1.3.26-1U80_5cl.i386.rpm ADDITIONAL INSTRUCTIONS Users of Conectiva Linux version 6.0 or higher may use apt to perform upgrades of RPM packages: - add the following line to /etc/apt/sources.list if it is not there yet (you may also use linuxconf to do this): rpm [cncbr] ftp://atualizacoes.conectiva.com.br 6.0/conectiva updates (replace 6.0 with the correct version number if you are not running CL6.0) - run: apt-get update - after that, execute: apt-get upgrade Detailed instructions reagarding the use of apt and upgrade examples can be found at http://distro.conectiva.com.br/atualizacoes/#apt?idioma=en - ------------------------------------------------------------------------- All packages are signed with Conectiva's GPG key.
