|Gentoo Linux Security Advisory
Title: FireHOL: Insecure temporary file creation (GLSA 200502-01)
Date: February 01, 2005
Updated: May 22, 2006
FireHOL is vulnerable to symlink attacks, potentially allowing a local user to overwrite arbitrary files.
FireHOL is an iptables rules generator.
Vulnerable: < 1.224
Unaffected: >= 1.224
Architectures: All supported architectures
FireHOL insecurely creates temporary files with predictable names.
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.
There is no known workaround at this time.
All FireHOL users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-firewall/firehol-1.224"
