CentOS 4 : httpd (CESA-2007:0747)

medium Nessus Plugin ID 67056

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated httpd packages that fix a security issue, various bugs, and add enhancements are now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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 :

* 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.

* 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.

* mod_proxy did not correctly handle percent-encoded characters (ie %20) when configured as a reverse proxy.

* invalid HTTP status codes could be logged if output filters returned errors.

* the 'ProxyTimeout' directive was not inherited across virtual host definitions.

* in some cases the Content-Length header was dropped from HEAD responses. This resulted in certain sites not working correctly with mod_proxy, such as www.windowsupdate.com.

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.

Solution

Update the affected httpd packages.
