Security Advisories and Notifications


Subject: Security Advisory (BEA08-201.00)
From: Oracle Corporation
Minor Subject: Multiple Security Vulnerabilities in the Java Runtime Environment
Product(s) Affected: BEA JRockit R27.5.0 or prior

Threat level: High
Multiple security vulnerabilities found. Possible remote attacks involve sending malicious XML code or a corrupted picture file to an application, or elevating privileges of downloaded malicious applications.

Severity: High
An attacker could elevate their privileges or execute arbitrary code. An application could be vulnerable to Denial of Service (DoS) attacks or exposure of URL resources.

Problems were identified that could potentially cause security vulnerabilities in certain versions of JRockit. Patches are available to correct these problems (see Section II). Oracle treats potential security problems with a high degree of urgency and endeavors to take appropriate steps to help ensure the security of our customers' systems. As a result, Oracle strongly suggests the following actions:

I. Read the following advisory.
II. Apply the suggested action if any (most users will not be affected).
III. If you know of any additional users interested in future security advisories, please forward them the registration instructions included in this advisory.

I. Advisory

This is a combined security advisory for Sun Security Alerts #231246, #231261, #233322, #233324 and #233325.


Sun Security Alert # 231246
A Vulnerability in the Java Runtime Environment XML Parsing Code May Allow URL Resources to be Accessed.

The Java Runtime Environment (JRE) by default allows external entity references to be processed. To turn off processing of external entity references, sites can set the "external general entities" property to FALSE. This property is provided since it may be possible to leverage the processing of external entity references to access certain URL resources (such as some files and web pages) or create a Denial of Service (DoS) condition on the system running the JRE. A defect in the JRE allows external entity references to be processed even when the "external general entities" property is set to FALSE.

For this vulnerability to be exploited, a trusted application needs to process XML data that contains malicious content. This vulnerability cannot be exploited through an untrusted applet or untrusted Java Web Start application.

Affected Releases:
  • JRockit R27.5.0 JDK and JRE 6 Update 3 and earlier

Sun Microsystems advised of this JRE vulnerability at:
http://sunsolve.sun.com/search/document.do?assetkey=1-66-231246-1


Sun Security Alert # 231261
Two Vulnerabilities in the Java Runtime Environment May Independently Allow an Untrusted Application or Applet to Elevate Privileges.

Two vulnerabilities in the Java Runtime Environment may independently allow an untrusted application or applet that is downloaded from a website to elevate its privileges. For example, the application or applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted application or applet.

Affected Releases:
  • JRockit R27.4.0 JDK and JRE 6 Update 1 and earlier
  • JRockit R27.4.0 JDK and JRE 5.0 Update 13 and earlier
Note: These vulnerabilities have already been fixed in JRockit R27.5.0.

Sun Security Alert # 233322
Security Vulnerability in the Java Runtime Environment With the Processing of XSLT Transformations.

A security vulnerability in the Java Runtime Environment (JRE) with the processing of XSLT transformations may allow an untrusted applet or application that is downloaded from a website to elevate its privileges. For example, an applet may read certain unauthorized URL resources (such as some files and web pages) or potentially execute arbitrary code. This vulnerability may also be exploited to create a Denial-of-Service (DoS) condition by causing the JRE to crash.

Note: This Vulnerability only affects applets.

Affected Releases:
  • JRockit R27.5.0 JDK and JRE 6 Update 3 and earlier
  • JRockit R27.5.0 JDK and JRE 5.0 Update 14 and earlier
  • JRockit R27.5.0 SDK and JRE 1.4.2_16 and earlier

Sun Microsystems advised of this JRE vulnerability at:
http://sunsolve.sun.com/search/document.do?assetkey=1-66-233322-1


Sun Security Alert # 233324
A Security Vulnerability in the Java Plug-in May Allow an Untrusted Applet to Elevate Privileges.

A security vulnerability in the Java Plug-in may allow an applet that is downloaded from a website to bypass the same origin policy and leverage this flaw to execute local applications that are accessible to the user running the untrusted applet.

Note: This Vulnerability only affects applets.

Affected Releases:
  • JRockit R27.5.0 JDK and JRE 6 Update 3 and earlier
  • JRockit R27.5.0 JDK and JRE 5.0 Update 14 and earlier
  • JRockit R27.5.0 SDK and JRE 1.4.2_16 and earlier

Sun Microsystems advised of this JRE vulnerability at:
http://sunsolve.sun.com/search/document.do?assetkey=1-66-233324-1


Sun Security Alert # 233325
Vulnerabilities in the Java Runtime Environment Image Parsing Library.

A vulnerability in the Java Runtime Environment image parsing library may allow an untrusted application or applet that is downloaded from a website to elevate its privileges. For example, the application or applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted application or applet.

Two vulnerabilities in the color management library may allow an untrusted applet or application or applet to cause the Java Runtime Environment to crash, which is a type of Denial of Service (DoS).

Affected Releases:
  • JRockit R27.5.0 JDK and JRE 6 Update 3 and earlier
  • JRockit R27.5.0 JDK and JRE 5.0 Update 14 and earlier
