Slackware 8.1-10.0: 2004-299-01 Moderate: Apache Heap Overflow Fix

slackware
Calendar Grey October 26, 2004
Dist Slackware Esm H88
Fresh updates for Apache and mod_ssl released for Slackware addressing security vulnerabilities in mod_proxy and enhancing cipher specifications.
New apache and mod_ssl packages are available for Slackware 8.1, 9.0, 9.1, 10.0, and -current to fix security issues

Summary

Here are the details from the Slackware 10.0 ChangeLog: patches/packages/apache-1.3.32-i486-1.tgz: Upgraded to apache-1.3.32. This addresses a heap-based buffer overflow in mod_proxy by rejecting responses from a remote server with a negative Content-Length. The flaw could crash the Apache child process, or possibly allow code to be executed as the Apache user (but only if mod_proxy is actually in use on the server). For more details, see: https://www.cve.org/CVERecord?id=CAN-2004-0492 (* Security fix *) patches/packages/mod_ssl-2.8.21_1.3.32-i486-1.tgz: Upgraded to mod_ssl-2.8.21-1.3.32. Don't allow clients to bypass cipher requirements, possibly negotiating a connection that the server does not consider secure enough. For more details, see: https://www.cve.org/CVERecord?id=CAN-2004-0885 (* Security fix *) patches/packages/php-4.3.9-i486-1.tgz: Upgraded to php-4.3.9.

Installation Instructions

Installation instructions: First, stop apache: # apachectl stop Next, upgrade the Apache package as root: # upgradepkg apache-1.3.32-i486-1.tgz For mod_ssl users, IMPORTANT: Backup any keys/certificates you wish to save for mod_ssl (in /etc/apache/ssl.*), then upgrade mod_ssl: # upgradepkg mod_ssl-2.8.21_1.3.32-i486-1.tgz If necessary, restore any mod_ssl config files. If your site uses PHP, you may wish to upgrade to the new package containing the latest version of PHP4. It wasn't clear to me if the biggest bugfix (a GPC input handling flaw) was really a security issue, but figured upgrading PHP for all supported versions of Slackware couldn't hurt. To upgrade PHP: # upgradepkg php-4.3.9-i486-1.tgz Finally, restart apache: # apachectl start Or, if you're running a secure server with mod_ssl: # apachectl startssl
