GLSA-200501-44 : ncpfs: Multiple vulnerabilities

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200501-44
(ncpfs: Multiple vulnerabilities)

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.

Solution :

All ncpfs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-fs/ncpfs-2.2.6'

Risk factor :

High / CVSS Base Score : 7.5
