USN-1263-1: IcedTea-Web, OpenJDK 6 vulnerabilities

16 November 2011

icedtea-web, openjdk-6, openjdk-6b18 vulnerabilities

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

Multiple OpenJDK 6 and IcedTea-Web vulnerabilities have been fixed.

Software Description

  • icedtea-web - A web browser plugin to execute Java applets
  • openjdk-6 - Open Source Java implementation
  • openjdk-6b18 - Open Source Java implementation

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)
