CVE-2008-3440

Estado: ModificadaAlta (7.5)—

Sun Java 1.6.0_03 and earlier versions, and possibly later versions, does not properly verify the authenticity of updates, which allows man-in-the-middle attackers to execute arbitrary code via a Trojan horse update, as demonstrated by evilgrade and DNS cache poisoning.
