GLSA-200505-18 : Net-SNMP: fixproc insecure temporary file creation

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200505-18
(Net-SNMP: fixproc insecure temporary file creation)

The fixproc application of Net-SNMP creates temporary files with
predictable filenames.

Impact :

A malicious local attacker could exploit a race condition to change the
content of the temporary files before they are executed by fixproc,
possibly leading to the execution of arbitrary code. A local attacker
could also create symbolic links in the temporary files directory,
pointing to a valid file somewhere on the filesystem. When fixproc is
executed, this would result in the file being overwritten.

Workaround :

There is no known workaround at this time.

Solution :

All Net-SNMP users should upgrade to the latest available version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-analyzer/net-snmp-5.2.1-r1'

Risk factor :

Critical / CVSS Base Score : 10.0
