  Severity: Normal
     Title: ncpfs: Multiple vulnerabilities

      Bugs: #77414

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"
