                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated icecast packages are available
Advisory ID:       RHSA-2002:063-05
Issue date:        2002-04-11
Updated on:        2002-04-24
Product:           Red Hat Powertools
Keywords:          icecast buffer overflow DoS long get request
Cross references:  
Obsoletes:         RHSA-2001:004
---------------------------------------------------------------------

1. Topic:

Updated icecast packages are available which fix a number of security
issues.

2. Relevant releases/architectures:

Red Hat Powertools 7.0 - alpha, i386

Red Hat Powertools 7.1 - alpha, i386

3. Problem description:

Icecast is a mp3-based broadcasting system. Buffer overflows in
Icecast 1.3.11 and earlier allow remote attackers to execute
arbitrary code via a long HTTP GET request. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2002-0177 to this issue.

Additional buffer overflow vulnerabilities exist in previous versions
of Icecast that are also fixed by this update.  These vulnerabilities
can cause denial of service attacks as well as arbitrary code
execution. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the names CAN-2001-0784, CAN-2001-1083,
CAN-2001-1229, and CAN-2001-1230 to these issues.

Users of Icecast are advised to update to the errata packages
containing Icecast 1.3.12 which is not vulnerable to 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 Red Hat Network.
Many people find this an easier way to apply updates.  To use Red Hat
Network, launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:

You can verify each package with the following command:
    rpm --checksig  <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
    rpm --checksig --nogpg <filename>
