Synopsis
========

The ncpfs utilities contain multiple flaws, potentially resulting in
the remote execution of arbitrary code or local file access with
elevated privileges.

Background
==========

ncpfs is a NCP protocol network filesystem driver that allows access to
NetWare services, to mount volumes of NetWare servers or print to
NetWare print queues.

Affected packages
=================

    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  net-fs/ncpfs       < 2.2.6                               >= 2.2.6

Description
===========

Erik Sjolund discovered two vulnerabilities in the programs bundled
with ncpfs: there is a potentially exploitable buffer overflow in
ncplogin (CAN-2005-0014), and due to a flaw in nwclient.c, utilities
using the NetWare client functions insecurely access files with
elevated privileges (CAN-2005-0013).

Impact
======

The buffer overflow might allow a malicious remote NetWare server to
execute arbitrary code on the NetWare client. Furthermore, a local
attacker may be able to create links and access files with elevated
privileges using SUID ncpfs utilities.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All ncpfs users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/ncpfs-2.2.6"

- 漏洞讨论

Multiple remote vulnerabilities affect ncpfs. The utility fails to manage access privileges securely and to validate the length of user-supplied strings before copying them into finite process buffers.

The first issue is a remote buffer-overflow vulnerability. The second issue is an access-validation issue due to the setuid privileges of ncpfs utilities.

An attacker may leverage these issues to execute arbitrary code with the privileges of the affected application and to access arbitrary files with the escalated privileges.
