User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
RedHat Linux Updated Apache httpd packages that correct three security issues are now available for Red Hat Enterprise Linux 5.The Apache HTTP Server did not verify that a process was an Apache child process before sending it signals. A local attacker with the ability to run scripts on the Apache HTTP Server could manipulate the scoreboard and cause arbitrary processes to be terminated which could lead to a denial of service. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

                   Red Hat Security Advisory

Synopsis:          Moderate: httpd security update
Advisory ID:       RHSA-2007:0556-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2007-0556.html
Issue date:        2007-06-26
Updated on:        2007-06-26
Product:           Red Hat Enterprise Linux
CVE Names:         CVE-2006-5752 CVE-2007-1863 CVE-2007-3304 
- ---------------------------------------------------------------------

1. Summary:

Updated Apache httpd packages that correct three security issues 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 Web server.

The Apache HTTP Server did not verify that a process was an Apache child
process before sending it signals. A local attacker with the ability to run
scripts on the Apache HTTP Server could manipulate the scoreboard and cause
arbitrary processes to be terminated which could lead to a denial of
service (CVE-2007-3304).  This issue is not exploitable on Red Hat
Enterprise Linux 5 if using the default SELinux targeted policy.

A flaw was found in the Apache HTTP Server mod_status module. On sites
where the server-status page is publicly accessible and ExtendedStatus is
enabled this could lead to a cross-site scripting attack. On Red Hat
Enterprise Linux the server-status page is not enabled by default and it is
best practice to not make this publicly available. (CVE-2006-5752)

A bug was found in the Apache HTTP Server mod_cache module. On sites where
caching is enabled, a remote attacker could send a carefully crafted
request that would cause the Apache child process handling that request to
crash. This could lead to a denial of service if using a threaded
Multi-Processing Module. (CVE-2007-1863)

Users of httpd should upgrade to these updated packages, which contain
backported patches to correct these issues. Users should restart Apache
after installing this update.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.  

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

244658 - CVE-2007-1863 httpd mod_cache segfault
245111 - CVE-2007-3304 httpd scoreboard lack of PID protection
245112 - CVE-2006-5752 httpd mod_status XSS
