cadaver security update

An updated cadaver package is now available that fixes a vulnerability in
neon which could be exploitable by a malicious DAV server.

cadaver is a command-line WebDAV client that uses inbuilt code from neon,
an HTTP and WebDAV client library.

Stefan Esser discovered a flaw in the neon library which allows a heap
buffer overflow in a date parsing routine. An attacker could create
a malicious WebDAV server in such a way as to allow arbitrary code
execution on the client should a user connect to it using cadaver. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0398 to this issue.

Users of cadaver are advised to upgrade to this updated package, which
contains a patch correcting this issue.

This issue does not affect Red Hat Enterprise Linux 3.

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.

If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
