                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated htdig packages are available
Advisory ID:       RHSA-2001:139-04
Issue date:        2001-10-24
Updated on:        2001-10-30
Product:           Red Hat Linux
Keywords:          htdig CGI htsearch DOS configuration file -c switch security
Cross references:   CGI abuses : ht://Dig's htsearch potential exposure/dos
Obsoletes:         
---------------------------------------------------------------------

1. Topic:

Updated ht://dig packages fix a DOS attack and a potential (yet unlikely)
security problem.

2. Relevant releases/architectures:

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386

3. Problem description:

In the previous version, the htsearch CGI script used to accept the -c
switch remotely--asking htdig to use a different configuration file. The
update removes this potential exploit.

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.
