---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated analog packages are available
Advisory ID:       RHSA-2001:017-03
Issue date:        2001-02-23
Updated on:        2001-02-23

---------------------------------------------------------------------

1. Topic:

Updated analog packages are available which fix a buffer overflow
vulnerability.

2. Relevant releases/architectures:

Red Hat Secure Web Server 2.0 - i386

3. Problem description:

Previous releases of analog were vulnerable to a buffer overflow
vulnerability where a malicious user could use an ALIAS command to
construct very long strings which were not checked for length.

This bug was discovered by the program author, and there is no known
exploit.

4. Solution:

To update all RPMs for your particular architecture, run:

rpm -Fvh 

where  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 directly *only* contains 
the desired RPMs.

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



6. RPMs required:

Red Hat Secure Web Server 2.0:

SRPMS: 
ftp://updates.Red Hat.com/secureweb/2.0/SRPMS/analog-4.16-1.src.rpm

i386: 
ftp://updates.Red Hat.com/secureweb/2.0/i386/analog-4.16-1.i386.rpm 
ftp://updates.Red Hat.com/secureweb/2.0/i386/analog-form-4.16-1.i386.rpm


7. Verification:

MD5 sum                           Package Name
--------------------------------------------------------------------------
a9a47be6fa6230bd29db2f4ff36f9f98  2.0/SRPMS/analog-4.16-1.src.rpm
5e52037dfd712a36a0aaec4b60bfba35  2.0/i386/analog-4.16-1.i386.rpm
d7e7b05487b8cc744d90de91e0e184eb  2.0/i386/analog-form-4.16-1.i386.rpm

These packages are GPG signed by Red Hat, Inc. for security.  Our key
is available at:
     http://www.Red Hat.com/corp/contact.html

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
