Ubuntu Security Notice USN-1263-2
January 24, 2012

openjdk-6, openjdk-6b18 regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

USN-1263-1 caused a regression when using OpenJDK 6's SSL/TLS
implementation.

Software Description:
- openjdk-6: Open Source Java implementation
- openjdk-6b18: Open Source Java implementation

Details:

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.

Original advisory details:

 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)
