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.

<description>
|
|
<p>
|
|
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.
|
|
</p>
|
|
</description>
|
|
<impact type="high">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ncpfs users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-fs/ncpfs-2.2.5"</code>
