Integer overflow in the unpack200 utility in Sun Java Runtime Environment (JRE) in JDK and JRE 6 before Update 15, and JDK and JRE 5.0 before Update 20, allows context-dependent attackers to gain privileges via unspecified length fields in the header of a Pack200-compressed JAR file, which leads to a heap-based buffer overflow during decompression.

The audio system in Sun Java Runtime Environment (JRE) in JDK and JRE 6 before Update 15, and JDK and JRE 5.0 before Update 20, does not prevent access to java.lang.System properties by (1) untrusted applets and (2) Java Web Start applications, which allows context-dependent attackers to obtain sensitive information by reading these properties.

Heap-based buffer overflow in Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier might allow remote attackers to execute arbitrary code via a crafted TrueType font file.

The "Java Update" feature for Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier does not verify the signature of the JRE that is downloaded, which allows remote attackers to execute arbitrary code via DNS man-in-the-middle attacks.

Stack-based buffer overflow in Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows locally-launched and possibly remote untrusted Java applications to execute arbitrary code via a JAR file with a long Main-Class manifest entry.

The Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier does not properly enforce context of ZoneInfo objects during deserialization, which allows remote attackers to run untrusted applets and applications in a privileged context, as demonstrated by "deserializing Calendar objects".

Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier accepts UTF-8 encodings that are not the "shortest" form, which makes it easier for attackers to bypass protection mechanisms for other applications that rely on shortest-form UTF-8 encodings.

Unspecified vulnerability in Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows untrusted applications and applets to list the contents of the operating user's directory via unknown vectors.

Unspecified vulnerability in Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier, when using Kerberos authentication, allows remote attackers to cause a denial of service (OS resource consumption) via unknown vectors.

Unspecified vulnerability in Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows untrusted applets to read arbitrary files and make unauthorized network connections via unknown vectors related to applet classloading, aka 6716217.

Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows remote attackers to make unauthorized network connections and hijack HTTP sessions via a crafted file that validates as both a GIF and a Java JAR file, aka "GIFAR" and CR 6707535.

Unspecified vulnerability in the BasicService for Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows untrusted downloaded applications to cause local files to be displayed in the browser of the user of the untrusted application via unknown vectors, aka 6767668.

Unspecified vulnerability in Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier, and JDK and JRE 5.0 Update 16 and earlier, allows untrusted JWS applications to obtain the pathname of the JWS cache and the application username via unknown vectors, aka CR 6727071.

Unspecified vulnerability in Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows untrusted JWS applications to gain privileges to access local files or applications via unknown vectors, aka 6727081.

Unspecified vulnerability in Java Web Start (JWS) and Java Plug-in with Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allows untrusted JWS applications to perform network connections to unauthorized hosts via unknown vectors, aka CR 6727079.

Sun Java Web Start and Java Plug-in for JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; and SDK and JRE 1.4.2_18 and earlier allow remote attackers to execute arbitrary code via a crafted jnlp file that modifies the (1) java.home, (2) java.ext.dirs, or (3) user.home System Properties, aka "Java Web Start File Inclusion" and CR 6694892.

Unspecified vulnerability in the Java Management Extensions (JMX) management agent in Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 6 and earlier and JDK and JRE 5.0 Update 15 and earlier, when local monitoring is enabled, allows remote attackers to "perform unauthorized operations" via unspecified vectors.
