[GLSA]

Gentoo Linux Security Advisory

Title: ncpfs: Multiple vulnerabilities (GLSA 200501-44)
Severity: normal
Exploitable: remote and local
Date: January 30, 2005
Bug(s): #77414
ID: 200501-44

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: net-fs/ncpfs
Vulnerable: < 2.2.6
Unaffected: >= 2.2.6
Architectures: All supported architectures


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:
