USN-3186-1

It was discovered that iucode-tool incorrectly handled certain microcodes when using the -tr loader. If a user were tricked into processing a specially crafted microcode, a remote attacker could use this issue to cause iucode-tool to crash, resulting in a denial of service, or possibly execute arbitrary code.
