               Fedora Legacy Update Advisory

Synopsis:          Updated cyrus-sasl resolves security vulnerabilities
Advisory ID:       FLSA:2137
Issue date:        2005-02-17
Product:           Red Hat Linux
                   Fedora Core
Keywords:          Security
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=2137
CVE Names:         CAN-2004-0884
-----------------------------------------------------------------------


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

Updated cyrus-sasl packages that fix a security vulnerability are now
available.

2. Relevant releases/architectures:

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

3. Problem description:

The cyrus-sasl package contains the Cyrus implementation of SASL.
SASL is the Simple Authentication and Security Layer, a method for
adding authentication support to connection-based protocols.

At application startup, libsasl and libsasl2 attempts to build a list
of all available SASL plug-ins which are available on the system.  To do
so, the libraries search for and attempt to load every shared library found
within the plug-in directory.  This location can be set with the SASL_PATH
environment variable.

In situations where an untrusted local user can affect the environment of a
privileged process, this behavior could be exploited to run arbitrary code
with the privileges of a setuid or setgid application.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0884 to this issue.

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.
