Background ========== 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. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/ncpfs < 2.2.6 >= 2.2.6 Description =========== 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. Resolution ========== All ncpfs users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/ncpfs-2.2.6" References ========== [ 1 ] CAN-2005-0013 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0013 [ 2 ] CAN-2005-0014 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0014 [ 3 ] ncpfs ChangeLog ftp://platan.vc.cvut.cz/pub/linux/ncpfs/Changes-2.2.6 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-44.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
