Unspecified vulnerability in Java Runtime Environment in Java JDK and JRE 5.0 Update 3 and earlier allows remote attackers to escape the Java sandbox and access arbitrary files or execute arbitrary applications via unknown attack vectors involving untrusted Java applets.
Sun Java Runtime Environment (JRE) 1.x before 1.4.2_11 and 1.5.x before 1.5.0_06, and as used in multiple web browsers, allows remote attackers to cause a denial of service (application crash) via deeply nested object arrays, which are not properly handled by the garbage collector and trigger invalid memory accesses.
