Jason Hoover discovered that migrationtools, a collection of scripts
to migrate user data to LDAP creates several temporary files insecurely,
which might lead to denial of service through a symlink attack.
For the stable distribution (sarge) this problem has been fixed in
version 46-1sarge1.
For the unstable distribution (sid) this problem has been fixed in
version 46-2.1.
We recommend that you upgrade your migrationtools package.
