Firewall Builder: Privilege escalation — GLSA 201201-11

Insecure temporary file usage in Firewall Builder could allow attackers to overwrite arbitrary files.

Affected Packages

net-firewall/fwbuilder on all architectures
Affected versions < 3.0.7
Unaffected versions >= 3.0.7

Background

Firewall Builder is a GUI for easy management of multiple firewall platforms.

Description

Two vulnerabilities in Firewall Builder allow the iptables and fwb_install scripts to use temporary files insecurely.

Impact

A local attacker could possibly overwrite arbitrary files with the privileges of the user running Firewall Builder.

Workaround

There is no known workaround at this time.

Resolution

All Firewall Builder users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-firewall/fwbuilder-3.0.7"
 

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since March 09, 2010. It is likely that your system is already no longer affected by this issue.
