 packages fix two security issues

---------------------------------------------------------------------
               Fedora Legacy Update Advisory

Synopsis:          Updated httpd and mod_ssl packages fix two
                   security issues
Advisory ID:       FLSA:166941
Issue date:        2005-11-09
Product:           Red Hat Linux, Fedora Core
Keywords:          Bugfix
CVE Names:         CVE-2005-2700 CVE-2005-2728
---------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated mod_ssl and Apache httpd packages that correct two security
issues are now available.

The Apache HTTP Server is a popular and freely-available Web server.

The mod_ssl module provides strong cryptography for the Apache Web
server via the Secure Sockets Layer (SSL) and Transport Layer Security
(TLS) protocols.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386

3. Problem description:

A flaw was discovered in mod_ssl's handling of the "SSLVerifyClient"
directive. This flaw occurs if a virtual host is configured
using "SSLVerifyClient optional" and a directive "SSLVerifyClient
required" is set for a specific location. For servers configured in this
fashion, an attacker may be able to access resources that should
otherwise be protected, by not supplying a client certificate when
connecting. The Common Vulnerabilities and Exposures project assigned
the name CVE-2005-2700 to this issue.

A flaw was discovered in Apache httpd where the byterange filter would
buffer certain responses into memory. If a server has a dynamic
resource such as a CGI script or PHP script that generates a large
amount of data, an attacker could send carefully crafted requests in
order to consume resources, potentially leading to a Denial of Service.
(CVE-2005-2728)

Users of mod_ssl and Apache httpd should update to these errata packages
that contain backported patches to correct these issues.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which
are not installed but included in the list will not be updated.  Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.

Please note that this update is also available via yum and apt.  Many
people find this an easier way to apply updates.  To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.  This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
