GLSA-200501-44 : ncpfs: Multiple vulnerabilities
High Nessus Plugin ID 16435
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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).
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.
There is no known workaround at this time.
SolutionAll ncpfs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-fs/ncpfs-2.2.6'
