The remote host is missing an update to lookup-el announced via advisory DSA 1269-1. 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.

For the stable distribution (sarge) this problem has been fixed in version 1.4-3sarge1. For the testing distribution (etch) this problem has been fixed in version 1.4-5. For the unstable distribution (sid) this problem has been fixed in version 1.4-5. We recommend that you upgrade your lookup-el package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201269-1
