Vulnerability Assessment Details

[GLSA-200501-44] ncpfs: Multiple vulnerabilities

Vulnerability Assessment Summary
ncpfs: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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 (CVE-2005-0014), and due to a flaw in nwclient.c, utilities
using the NetWare client functions insecurely access files with
elevated rights (CVE-2005-0013).

Impact

The buffer overflow might permit 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
rights using SUID ncpfs utilities.

Workaround

There is no known workaround at this time.
