-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : apache SUMMARY : Format string vulnerability with mod_ssl DATE : 2004-08-06 12:18:00 ID : CLA-2004:857 RELEVANT RELEASES : 8 - ------------------------------------------------------------------------- DESCRIPTION Ralf S. Engelschall found[1] a dangerous call[2] to ssl_log function in ssl_engine_log.c that could allow remote attackers to execute arbitrary messages via format string specifiers in certain log messages for HTTPS. SOLUTION It is recommended that all Apache users upgrade their packages. IMPORTANT: it is necessary to manually restart the httpd server after upgrading the packages. In order to do this, execute the following as root: # service httpd stop (wait a few seconds and check with "pidof httpd" if there are any httpd processes running. On a busy webserver this could take a little longer) # service httpd start UPDATED PACKAGES ftp://atualizacoes.conectiva.com.br/8/SRPMS/apache-1.3.28-1U80_5cl .src.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/apache-1.3.28-1U80_5cl.i 386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/apache-devel-1.3.28-1U8 0_5cl.i386.rpm ftp://atualizacoes.conectiva.com.br/8/RPMS/apache-doc-1.3.28-1U80_ 5cl.i386.rpm ADDITIONAL INSTRUCTIONS The apt tool can be used to perform RPM packages upgrades: - run: apt-get update - after that, execute: apt-get upgrade Detailed instructions regarding 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.
