libpam-tmpdir 0.09 (i386 binary) in ubuntu quantal

 Many programs use $TMPDIR for storing temporary files. Not
 all of them are good at securing the permissions of those
 files. libpam-tmpdir sets $TMPDIR and $TMP for PAM sessions
 and sets the permissions quite tight. This helps system
 security by having an extra layer of security, making such
 symlink attacks and other /tmp based attacks harder or
 impossible
