| Description: | The Apache HTTP Server is a popular and freely-available Web server.
A flaw was found in the Apache HTTP Server mod_proxy module. On sites where a reverse proxy is configured, a remote attacker could send a carefully crafted request that would cause the Apache child process handling that request to crash. On sites where a forward proxy is configured, an attacker could cause a similar crash if a user could be persuaded to visit a malicious site using the proxy. This could lead to a denial of service if using a threaded Multi-Processing Module. (CVE-2007-3847)
As well, these updated packages fix the following bugs:
Set-Cookie headers with a status code of 3xx are not forwarded to clients when the "ProxyErrorOverride" directive is enabled. These responses are overridden at the proxy. Only the responses with status codes of 4xx and 5xx are overridden in these updated packages.
the default "/etc/logrotate.d/httpd" script incorrectly invoked the kill command, instead of using the "/sbin/service httpd restart" command. If you configured the httpd PID to be in a location other than "/var/run/httpd.pid", the httpd logs failed to be rotated. This has been resolved in these updated packages.
the "ProxyTimeout" directive was not inherited across virtual host definitions.
the logresolve utility was unable to read lines longer the 1024 bytes.
This update adds the following enhancements:
a new configuration option has been added, "ServerTokens Full-Release", which adds the package release to the server version string, which is returned in the "Server" response header.
a new module has been added, mod_version, which allows configuration files to be written containing sections, which are evaluated only if the version of httpd used matches a specified condition.
Users of httpd are advised to upgrade to these updated packages, which resolve these issues and add these enhancements.
