<title>ncpfs: Multiple vulnerabilities</title>
<synopsis>
The ncpfs utilities contain multiple flaws, potentially resulting in the
remote execution of arbitrary code or local file access with elevated
privileges.

<p>
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.

<description>
<p>
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).
</p>
</description>
<impact type="normal">
<p>
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.
</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 &quot;&gt;=net-fs/ncpfs-2.2.6&quot;</code>
</resolution>
