USN-1263-1 fixed vulnerabilities in OpenJDK 6. The upstream patch for the chosen plaintext attack on the block-wise AES encryption algorithm (CVE-2011-3389) introduced a regression that caused TLS/SSL connections to fail when using certain algorithms. This update fixes the problem.

We apologize for the inconvenience.

Deepak Bhole discovered a flaw in the Same Origin Policy (SOP) implementation in the IcedTea web browser plugin. This could allow a remote attacker to open connections to certain hosts that should not be permitted. (CVE-2011-3377)

Juliano Rizzo and Thai Duong discovered that the block-wise AES encryption algorithm block-wise as used in TLS/SSL was vulnerable to a chosen-plaintext attack. This could allow a remote attacker to view confidential data. (CVE-2011-3389)

It was discovered that a type confusion flaw existed in the in the Internet Inter-Orb Protocol (IIOP) deserialization code. A remote attacker could use this to cause an untrusted application or applet to execute arbitrary code by deserializing malicious input. (CVE-2011-3521)

It was discovered that the Java scripting engine did not perform SecurityManager checks. This could allow a remote attacker to cause an untrusted application or applet to execute arbitrary code with the full privileges of the JVM.
(CVE-2011-3544)

It was discovered that the InputStream class used a global buffer to store input bytes skipped. An attacker could possibly use this to gain access to sensitive information.
(CVE-2011-3547)

It was discovered that a vulnerability existed in the AWTKeyStroke class. A remote attacker could cause an untrusted application or applet to execute arbitrary code.
(CVE-2011-3548)

It was discovered that an integer overflow vulnerability existed in the TransformHelper class in the Java2D implementation. A remote attacker could use this cause a denial of service via an application or applet crash or possibly execute arbitrary code. (CVE-2011-3551)

It was discovered that the default number of available UDP sockets for applications running under SecurityManager restrictions was set too high. A remote attacker could use this with a malicious application or applet exhaust the number of available UDP sockets to cause a denial of service for other applets or applications running within the same JVM. (CVE-2011-3552)

It was discovered that Java API for XML Web Services (JAX-WS) could incorrectly expose a stack trace. A remote attacker could potentially use this to gain access to sensitive information. (CVE-2011-3553)

It was discovered that the unpacker for pack200 JAR files did not sufficiently check for errors. An attacker could cause a denial of service or possibly execute arbitrary code through a specially crafted pack200 JAR file.
(CVE-2011-3554)

It was discovered that the RMI registration implementation did not properly restrict privileges of remotely executed code. A remote attacker could use this to execute code with elevated privileges. (CVE-2011-3556, CVE-2011-3557)

It was discovered that the HotSpot VM could be made to crash, allowing an attacker to cause a denial of service or possibly leak sensitive information. (CVE-2011-3558)

It was discovered that the HttpsURLConnection class did not properly perform SecurityManager checks in certain situations. This could allow a remote attacker to bypass restrictions on HTTPS connections. (CVE-2011-3560).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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-2011-3556)

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-2011-3557)

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-2011-3521)

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-2011-3544)

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-2011-3548)

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-2011-3551)

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-2011-3554)

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-2011-3560)

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-2011-3389)

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-2011-3547)

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-2011-3558)

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-2011-3553)

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.
(CVE-2011-3552)
