Fedora Legacy Update Advisory

Synopsis: Updated httpd, apache and mod_ssl packages fix
security issues
Advisory ID: FLSA:2148
Issue date: 2004-12-03
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2148
CVE Names: CAN-2004-0885 CAN-2004-0940 CAN-2004-0942
-----------------------------------------------------------------------


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

Updated httpd packages that include fixes for security issues are now available.

The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server.

2. Relevant releases/architectures:

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

3. Problem description:

An issue has been discovered in the mod_ssl module when configured to use the "SSLCipherSuite" directive in directory or location context. If a particular location context has been configured to require a specific set of cipher suites, then a client will be able to access that location using any cipher suite allowed by the virtual host configuration. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0885 to this issue.

Problems that apply to Red Hat Linux 7.3 only:

A buffer overflow in mod_include could allow a local user who is authorised to create server side include (SSI) files to gain the privileges of a httpd child. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0940 to this issue.

Problems that apply to Red Hat Linux 9 and Fedora Core 1 only:

An issue has been discovered in the handling of white space in request header lines using MIME folding. A malicious client could send a carefully crafted request, forcing the server to consume large amounts of memory, leading to a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0942 to this issue.

Users of the Apache HTTP server should upgrade to these updated packages, which contain patches that address 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.
