Subject: [gentoo-dev] /var/tmp world rwx?
Date: Fri, 03 Jan 2003 16:42:31 -0600 [thread overview]
Message-ID: <3E1611D7.5020400@seaplace.org> (raw)
I've been playing around with using tmpfs for /tmp and had it mounted
with my standard "noexec,nodev,nosuid" anti-hack security options. This
works fine for VI or other normal tools.
I wanted Portage to use it as well, to symbolically linked /var/tmp to /tmp.
That broke emerge. The "noexec" option prevents any builds from
working. That made me check one of my unmodified gentoo systems where I
spotted that /var/tmp was world read/execute. That's a security problem.
Any reason that /var/tmp can't be root read/execute only?
