GLSA-200501-44 : ncpfs: Multiple vulnerabilities

high Nessus Plugin ID 16435

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'
