                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated secureweb packages available
Advisory ID:       RHSA-2001:164-08
Issue date:        2001-12-05
Updated on:        2001-12-07
Product:           Red Hat Secure Web Server
Keywords:          secureweb directory listing
Cross references:  RHSA-2001:126
Obsoletes:         RHBA-2000:020

1. Topic:

Updated packages are now available for Red Hat Secure Web Server 3.2 (U.S.). 
These updates close a potential security hole which would present clients
with a listing of the contents of a directory instead of the contents of an
index file or the proper error message.

2. Relevant releases/architectures:

Red Hat Secure Web Server 3.2 - i386

3. Problem description:

By using a carefully constructed HTTP request, a server with
mod_negotiation and either mod_dir or mod_autoindex loaded could be tricked
into displaying a listing of the contents of a directory, despite the
presence of an index file.

The Common Vulnerabilities and Exposures project ( has
assigned the names CAN-2001-0730, and CAN-2001-0731 to these issues.

4. Solution:

The main secureweb package is provided as an rhmask file.  In order to
generate the actual secureweb RPM package, you will need the
secureweb-3.2-12 package file from the Secure Web Server CD.  Then, using
the rhmask command, generate the secureweb RPM package:

rhmask secureweb-3.2-12.i386.rpm secureweb-3.2.4-1.i386.rpm.rhmask

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

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.

5. Bug IDs fixed  (http://bugzilla.Red for more info):

6. RPMs required:

Red Hat Secure Web Server 3.2:


7. Verification:

MD5 sum                          Package Name
3097ba872708a54b64354a54a3e38771 3.2/en/secureweb/i386/secureweb-3.2.4-1.i386.rpm.rhmask
93f2a1bbe394454bf35c665b5ceebddf 3.2/en/secureweb/i386/secureweb-devel-3.2.4-1.i386.rpm
f819ce00eea66d0524cba6f92c7a661e 3.2/en/secureweb/i386/secureweb-manual-3.2.4-1.i386.rpm

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  

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
