Background ========== FireHOL is an iptables rules generator. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-firewall/firehol < 1.224 >= 1.224 Description =========== FireHOL insecurely creates temporary files with predictable names. Impact ====== A local attacker could create malicious symbolic links to arbitrary system files. When FireHOL is executed, this could lead to these files being overwritten with the rights of the user launching FireHOL, usually the root user. Workaround ========== There is no known workaround at this time. Resolution ========== All FireHOL users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-firewall/firehol-1.224" References ========== [ 1 ] FireHOL CVS log http://cvs.sourceforge.net/viewcvs.py/firehol/firehol/firehol.sh Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200502-01.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
