GLSA-200506-10 : LutelWall: 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-200506-10
(LutelWall: Insecure temporary file creation)

Eric Romang has discovered that the new_version_check() function
in LutelWall insecurely creates a temporary file when updating to a new
version.

Impact :

A local attacker could create symbolic links in the temporary file
directory, pointing to a valid file somewhere on the filesystem. When
the update script is executed (usually by the root user), this would
result in the file being overwritten with the rights of this user.

Workaround :

There is no known workaround at this time.

Solution :

All LutelWall users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-firewall/lutelwall-0.98'

Risk factor :

Low / CVSS Base Score : 2.1
