Advisory ID: FLSA:152904
Issue date: 2006-05-12

Keywords: Bugfix
CVE Names: CVE-2004-1079 CVE-2005-0013 CVE-2005-0014
---------------------------------------------------------------------



---------------------------------------------------------------------
1. Topic:

An updated ncpfs package is now available.

Ncpfs is a file system that understands the Novell NetWare(TM) NCP
protocol.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386
Fedora Core 3 - i386, x86_64

3. Problem description:

Buffer overflows were found in the nwclient program. An attacker, using
a long -T option, could possibly execute arbitrary code and gain
privileges. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-1079 to this issue.

A bug was found in the way ncpfs handled file permissions. ncpfs did not
sufficiently check if the file owner matched the user attempting to
access the file, potentially violating the file permissions. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2005-0013 to this issue.

A buffer overflow was found in the ncplogin program. A remote malicious
NetWare server could execute arbitrary code on a victim's machine. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-0014 to this issue.

All users of ncpfs are advised to upgrade to this updated package, which
contains backported fixes for 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 yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.
