Red Hat Security Advisory
Synopsis: Moderate: httpd security, bug fix, and enhancement update
Advisory ID: RHSA-2007:0746-04
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0746.html
Issue date: 2007-11-07
Updated on: 2007-11-07
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-3847
- ---------------------------------------------------------------------
1. Summary:
Updated httpd packages that fix a security issue, fix various bugs, and
add enhancements, are now available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
3. Problem 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.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
