Sun JRE 1.4.0_01

Sun SDK and Java Runtime Environment (JRE) 1.4.2 through 1.4.2_04, 1.4.1 through 1.4.1_07, and 1.4.0 through 1.4.0_04 allows untrusted applets and unprivileged servlets to gain privileges and read data from other applets via unspecified vectors related to classes in the XSLT processor, aka "XML sniffing."

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.

Sun Java Runtime Environment (JRE) and SDK 1.4.0_01 and earlier allows untrusted applets to access certain information within trusted applets, which allows attackers to bypass the restrictions of the Java security model.

Unspecified vulnerability in JNLPAppletlauncher in Sun Java SE, and SE for Business, in JDK and JRE 6 Update 14 and earlier and JDK and JRE 5.0 Update 19 and earlier; and Java SE for Business in SDK and JRE 1.4.2_21 and earlier; allows remote attackers to create or modify arbitrary files via vectors involving an untrusted Java applet that accesses an old version of JNLPAppletLauncher.

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.
