Synopsis
=======
ncpfs is vulnerable to a buffer overflow that could lead to local
execution of arbitrary code with elevated privileges.

Background
=========
ncpfs is a NCP protocol network filesystem that allows access to
Netware services, for example to mount volumes of NetWare servers or
print to NetWare print queues.

Affected packages
================
    -------------------------------------------------------------------
     Package       /  Vulnerable  /                         Unaffected
    -------------------------------------------------------------------
  1  net-fs/ncpfs       < 2.2.5                               >= 2.2.5

Description
==========
Karol Wiesek discovered a buffer overflow in the handling of the '-T'
option in the ncplogin and ncpmap utilities, which are both installed
as SUID root by default.

Impact
=====
A local attacker could trigger the buffer overflow by calling one of
these utilities with a carefully crafted command line, potentially
resulting in execution of arbitrary code with root privileges.

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-2.2.5"
