CVE-2007-4129 coolkey file and directory permission flaw
Steve Grubb reported: "It looks like coolkey creates /tmp/.pk11ipc1 as a
world writable directory without the sticky bit. And...it creates the files
under that potentially as world writable with the execute bit turned on or
uses the file without any sanity check. coolkey runs as root sometimes and
that makes it susceptible to doing symlink attacks."
I know some folks ship coolkey here, so we've set an embargo of 20070904,
but as it's low severity are happy to extend if anyone wishes.
CVE-2007-4129 for this issue.
Proposed patch from Bob Relyea attached.
