Background ========== Firewall Builder is a GUI for easy management of multiple firewall platforms. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-firewall/fwbuilder < 3.0.7 >= 3.0.7 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.
