fglrx-installer vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

LD_LIBRARY_PATH on 64bit systems. If a user were tricked into downloading
specially crafted libraries and running commands in the same directory,
a remote attacker could execute arbitrary code with user privileges.
