Binary package hint: lookup-el

[3] DSA-1269-1 (http://www.debian.org/security/2007/dsa-1269)

Quoting [2]:
"Tatsuya Kinoshita discovered that Lookup, a search interface to electronic
dictionaries on emacsen, creates a temporary file in an insecure fashion when
the ndeb-binary feature is used, which allows a local attacker to craft a
symlink attack to overwrite arbitrary files."

Quite old and already fixed in Debian since March, but only recently
reported at Gentoo, so I thought I might report it here, also. Maybe
applies for the older Ubuntu releases.
