<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.

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.

<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 ">=net-fs/ncpfs-2.2.6"</code>
|
|
</resolution>
