Multiple unspecified vulnerabilities in reflection APIs in Java SDK and JRE 1.4.2_08 and earlier and JDK and JRE 5.0 Update 3 and earlier allow remote attackers to escape the Java sandbox and access arbitrary files or execute arbitrary applications via unknown attack vectors, a different set of vulnerabilities than CVE-2005-3905. NOTE: this is associated with the "second and third issues" identified in SUNALERT:102003.

The Sun Java Plugin capability in Java 2 Runtime Environment (JRE) 1.4.2_01, 1.4.2_04, and possibly earlier versions, does not properly restrict access between Javascript and Java applets during data transfer, which allows remote attackers to load unsafe classes and execute arbitrary code by using the reflection API to access private Java packages.

readObject in (1) Java Runtime Environment (JRE) and (2) Software Development Kit (SDK) 1.4.0 through 1.4.2_05 allows remote attackers to cause a denial of service (JVM unresponsive) via crafted serialized data.
