A local attacker could possibly use this to cause a denial of service or possibly execute arbitrary code. Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. Various other issues were also addressed.
