RHSA-2012:0323: httpd security update



The Apache HTTP Server is a popular web server.It was discovered that the fix for CVE-2011-3368 (released viaRHSA-2011:1392) did not completely address the problem. An attacker couldbypass the fix and make a reverse proxy connect to an arbitrary server notdirectly accessible to the attacker by sending an HTTP version 0.9 request.(CVE-2011-3639)The httpd server included the full HTTP header line in the default errorpage generated when receiving an excessively long or malformed header.Malicious JavaScript running in the server's domain context could use thisflaw to gain access to httpOnly cookies. (CVE-2012-0053)An integer overflow flaw, leading to a heap-based buffer overflow, wasfound in the way httpd performed substitutions in regular expressions. Anattacker able to set certain httpd settings, such as a user permitted tooverride the httpd configuration for a specific directory using a".htaccess" file, could use this flaw to crash the httpd child process or,possibly, execute arbitrary code with the privileges of the "apache" user.(CVE-2011-3607)A flaw was found in the way httpd handled child process status information.A malicious program running with httpd child process privileges (such as aPHP or CGI script) could use this flaw to cause the parent httpd process tocrash during httpd service shutdown. (CVE-2012-0031)All httpd users should upgrade to these updated packages, which containbackported patches to correct these issues. After installing the updatedpackages, the httpd daemon will be restarted automatically.
