Security Fixes

CVE-2011-0862

Integer overflow flaws were found in the way Java2D parsed JPEG images and user-supplied fonts. An attacker could use these flaws to execute arbitrary code with the privileges of the user running an untrusted applet or application.

CVE-2011-0871

It was found that the MediaTracker implementation created Component instances with unnecessary access privileges. A remote attacker could use this flaw to elevate their privileges by utilizing an untrusted applet or application that uses Swing.

CVE-2011-0864

A flaw was found in the HotSpot component in OpenJDK. Certain bytecode instructions confused the memory management within the Java Virtual Machine (JVM), resulting in an applet or application crashing.

CVE-2011-0867

An information leak flaw was found in the NetworkInterface class. An untrusted applet or application could use this flaw to access information about available network interfaces that should only be available to privileged code.

CVE-2011-0868

An incorrect float-to-long conversion, leading to an overflow, was found in the way certain objects (such as images and text) were transformed in Java2D. A remote attacker could use this flaw to crash an untrusted applet or application that uses Java2D.

CVE-2011-0869

It was found that untrusted applets and applications could misuse a SOAP connection to incorrectly set global HTTP proxy settings instead of setting them in a local scope. This flaw could be used to intercept HTTP requests.

CVE-2011-0865

A flaw was found in the way signed objects were deserialized. If trusted and untrusted code were running in the same Java Virtual Machine (JVM), and both were deserializing the same signed object, the untrusted code could modify said object by using this flaw to bypass the validation checks on signed objects.

Security Fixes

CVE-2011-3556

A flaw was found in the Java RMI (Remote Method Invocation) registry implementation. A remote RMI client could use this flaw to execute arbitrary code on the RMI server running the registry.

CVE-2011-3557

A flaw was found in the Java RMI registry implementation. A remote RMI client could use this flaw to execute code on the RMI server with unrestricted privileges.

CVE-2011-3521

A flaw was found in the IIOP (Internet Inter-Orb Protocol) deserialization code. An untrusted Java application or applet running in a sandbox could use this flaw to bypass sandbox restrictions by deserializing specially-crafted input.

CVE-2011-3544

It was found that the Java ScriptingEngine did not properly restrict the privileges of sandboxed applications. An untrusted Java application or applet running in a sandbox could use this flaw to bypass sandbox restrictions.

CVE-2011-3548

A flaw was found in the AWTKeyStroke implementation. An untrusted Java application or applet running in a sandbox could use this flaw to bypass sandbox restrictions.

CVE-2011-3551

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the Java2D code used to perform transformations of graphic shapes and images. An untrusted Java application or applet running in a sandbox could use this flaw to bypass sandbox restrictions.

CVE-2011-3554

An insufficient error checking flaw was found in the unpacker for JAR files in pack200 format. A specially-crafted JAR file could use this flaw to crash the Java Virtual Machine (JVM) or, possibly, execute arbitrary code with JVM privileges.

CVE-2011-3560

It was found that HttpsURLConnection did not perform SecurityManager checks in the setSSLSocketFactory method. An untrusted Java application or applet running in a sandbox could use this flaw to bypass connection restrictions defined in the policy.

CVE-2011-3389

A flaw was found in the way the SSL 3 and TLS 1.0 protocols used block ciphers in cipher-block chaining (CBC) mode. An attacker able to perform a chosen plain text attack against a connection mixing trusted and untrusted data could use this flaw to recover portions of the trusted data sent over the connection.

CVE-2011-3547

Note

This update mitigates the CVE-2011-3389 issue by splitting the first application data record byte to a separate SSL/TLS protocol record. This mitigation may cause compatibility issues with some SSL/TLS implementations and can be disabled using the jsse.enableCBCProtection boolean property. This can be done on the command line by appending the flag "-Djsse.enableCBCProtection=false" to the java command.

An information leak flaw was found in the InputStream.skip implementation. An untrusted Java application or applet could possibly use this flaw to obtain bytes skipped by other threads.

CVE-2011-3558

A flaw was found in the Java HotSpot virtual machine. An untrusted Java application or applet could use this flaw to disclose portions of the VM memory, or cause it to crash.

CVE-2011-3553

The Java API for XML Web Services (JAX-WS) implementation in OpenJDK was configured to include the stack trace in error messages sent to clients. A remote client could possibly use this flaw to obtain sensitive information.

CVE-2011-3552

It was found that Java applications running with SecurityManager restrictions were allowed to use too many UDP sockets by default. If multiple instances of a malicious application were started at the same time, they could exhaust all available UDP sockets on the system.

BZ#722310

The java-1.6.0-openjdk package has been upgraded to the upstream version 1.10.4, which provides a number of bug fixes and enhancements over the previous version.

BZ#708201

Installing of OpenJDK or execution of a Java program, which was using other than terminal fonts, could have terminated unexpectedly with the following error:

Exception in thread "main"
java.lang.Error: Probable fatal error:No fonts found.

This happened because the fontconfig library was not installed and the font enumeration failed. With this update, OpenJDK depends on fontconfig and the problem no longer occurs.
