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 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.

Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier; JDK and JRE 5.0 Update 16 and earlier; SDK and JRE 1.4.2_18 and earlier; and SDK and JRE 1.3.1_23 and earlier creates temporary files with predictable file names, which allows attackers to write malicious JAR files via unknown vectors.

Integer 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; SDK and JRE 1.4.2_18 and earlier; and SDK and JRE 1.3.1_23 and earlier might allow remote attackers to execute arbitrary code via a crafted TrueType font file, which triggers a heap-based buffer overflow.

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.

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".

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.

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.

Buffer overflow in Sun Java Runtime Environment (JRE) in JDK and JRE 5.0 before Update 10, SDK and JRE 1.4.x before 1.4.2_18, and SDK and JRE 1.3.x before 1.3.1_23 allows context-dependent attackers to gain privileges via unspecified vectors related to font processing.

Multiple unspecified vulnerabilities in Sun Java Runtime Environment (JRE) in JDK and JRE 6 before Update 7, JDK and JRE 5.0 before Update 16, SDK and JRE 1.4.x before 1.4.2_18, and SDK and JRE 1.3.x before 1.3.1_23 allow remote attackers to violate the security model for an applet's outbound connections by connecting to localhost services running on the machine that loaded the applet.
