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 : Medium
