The IcedTea-Web project provides a Java web browser plug-in and an implementation of Java Web Start, which is based on the Netx project.
It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations.

A flaw was found in the same-origin policy implementation in the IcedTea-Web browser plug-in. A malicious Java applet could use this flaw to open network connections to hosts other than the originating host, violating the same-origin policy. (CVE-2011-3377)

All IcedTea-Web users should upgrade to these updated packages, which upgrade IcedTea-Web to version 1.0.6 to correct this issue. Web browsers using the IcedTea-Web browser plug-in must be restarted for this update to take effect.

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).

Security issues were identified and fixed in openjdk (icedtea6) and icedtea-web :

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality via unknown vectors related to Networking (CVE-2011-3547).

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability, related to AWT (CVE-2011-3548).

IcedTea6 prior to 1.10.4 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to 2D (CVE-2011-3551).

IcedTea6 prior to 1.10.4 allows remote attackers to affect integrity via unknown vectors related to Networking (CVE-2011-3552).

IcedTea6 prior to 1.10.4 allows remote authenticated users to affect confidentiality, related to JAXWS (CVE-2011-3553).

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors related to Scripting (CVE-2011-3544).

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors related to Deserialization (CVE-2011-3521).

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality, integrity, and availability via unknown vectors (CVE-2011-3554).

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.

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality via unknown vectors related to HotSpot (CVE-2011-3558).

IcedTea6 prior to 1.10.4 allows remote attackers to affect confidentiality, integrity, and availability, related to RMI (CVE-2011-3556).

IcedTea6 prior to 1.10.4 allows remote attackers to affect confidentiality, integrity, and availability, related to RMI (CVE-2011-3557).

IcedTea6 prior to 1.10.4 allows remote untrusted Java Web Start applications and untrusted Java applets to affect confidentiality and integrity, related to JSSE (CVE-2011-3560).

Deepak Bhole discovered a flaw in the Same Origin Policy (SOP) implementation in the IcedTea project Web browser plugin. A malicious applet could use this flaw to bypass SOP protection and open connections to any sub-domain of the second-level domain of the applet's origin, as well as any sub-domain of the domain that is the suffix of the origin second-level domain. For example, IcedTea-Web plugin allowed applet from some.host.example.com to connect to other.host.example.com, www.example.com, and example.com, as well as www.ample.com or ample.com. (CVE-2011-3377).

Several vulnerabilities have been discovered in OpenJDK, an implementation of the Oracle Java platform.

  - CVE-2011-3377     The IcedTea browser plugin included in the openjdk-6     package does not properly enforce the Same Origin Policy     on web content served under a domain name which has a     common suffix with the required domain name.

  - CVE-2011-3563     The Java Sound component did not properly check for     array boundaries. A malicious input or an untrusted Java     application or applet could use this flaw to cause Java     Virtual Machine to crash or disclose portion of its     memory.

  - CVE-2011-5035     The OpenJDK embedded web server did not guard against an     excessive number of a request parameters, leading to a     denial of service vulnerability involving hash     collisions.

  - CVE-2012-0497     It was discovered that Java2D did not properly check     graphics rendering objects before passing them to the     native renderer. This could lead to JVM crash or Java     sandbox bypass.

  - CVE-2012-0501     The ZIP central directory parser used by     java.util.zip.ZipFile entered an infinite recursion in     native code when processing a crafted ZIP file, leading     to a denial of service.

  - CVE-2012-0502     A flaw was found in the AWT KeyboardFocusManager class     that could allow untrusted Java applets to acquire     keyboard focus and possibly steal sensitive information.

  - CVE-2012-0503     The java.util.TimeZone.setDefault() method lacked a     security manager invocation, allowing an untrusted Java     application or applet to set a new default time zone.

  - CVE-2012-0505     The Java serialization code leaked references to     serialization exceptions, possibly leaking critical     objects to untrusted code in Java applets and     applications.

  - CVE-2012-0506     It was discovered that CORBA implementation in Java did     not properly protect repository identifiers (that can be     obtained using _ids() method) on certain Corba objects.
    This could have been used to perform modification of the     data that should have been immutable.

  - CVE-2012-0507     The AtomicReferenceArray class implementation did not     properly check if the array is of an expected Object[]     type. A malicious Java application or applet could use     this flaw to cause Java Virtual Machine to crash or     bypass Java sandbox restrictions.
