Synopsis ========
The ncpfs utilities contain multiple flaws, potentially resulting in the remote execution of arbitrary code or local file access with elevated privileges.
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"
