Sun Java Updates for Multiple Vulnerabilities
Original release date: December 05, 2008
Last revised: --
Source: US-CERT
Systems Affected
Sun Java Runtime Environment versions
* JDK and JRE 6 Update 10 and earlier
* JDK and JRE 5.0 Update 16 and earlier
* SDK and JRE 1.4.2_18 and earlier
* SDK and JRE 1.3.1_23 and earlier
Overview
Sun has released alerts to address multiple vulnerabilities
affecting the Sun Java Runtime Environment. The most severe of
these vulnerabilities could allow a remote attacker to execute
arbitrary code.
I. Description
The Sun Java Runtime Environment (JRE) allows users to run Java
applications in a browser or as standalone programs. Sun has
released updates to the Java Runtime Environment software to
address multiple vulnerabilities.
Sun released the following alerts to address these issues:
* 244986 : The Java Runtime Environment Creates Temporary Files
That Have "Guessable" File Names
* 244987 : Java Runtime Environment (JRE) Buffer Overflow
Vulnerabilities in Processing Image Files and Fonts May Allow
Applets or Java Web Start Applications to Elevate Their Privileges
* 244988 : Multiple Security Vulnerabilities in Java Web Start
and Java Plug-in May Allow Privilege Escalation
* 244989 : The Java Runtime Environment (JRE) "Java Update"
Mechanism Does Not Check the Digital Signature of the JRE that it
Downloads
* 244990 : A Buffer Overflow Vulnerability in the Java Runtime
Environment (JRE) May Allow Privileges to be Escalated
* 244991 : A Security Vulnerability in the Java Runtime
Environment (JRE) Related to Deserializing Calendar Objects May
Allow Privileges to be Escalated
* 245246 : The Java Runtime Environment UTF-8 Decoder May Allow
Multiple Representations of UTF-8 Input
* 246266 : Security Vulnerability in Java Runtime Environment May
Allow Applets to List the Contents of the Current User's Home
Directory
* 246286 : Security Vulnerability in the Java Runtime Environment
With Processing RSA Public Keys
* 246346 : A Security Vulnerability in Java Runtime Environment
(JRE) With Authenticating Users Through Kerberos May Lead to a
Denial of Service (DoS)
* 246366 : Security Vulnerabilities in the Java Runtime
Environment (JRE) JAX-WS and JAXB Packages may Allow Privileges to
be Escalated
* 246386 : A Security Vulnerability in Java Runtime Environment
(JRE) With Parsing of Zip Files May Allow Reading of Arbitrary
Memory Locations
* 246387 : A Security Vulnerability in the Java Runtime
Environment may Allow Code Loaded From the Local Filesystem to
Access LocalHost
II. Impact
The impacts of these vulnerabilities vary. The most severe of these
vulnerabilities allows a remote attacker to execute arbitrary code.
III. Solution
Apply an update from Sun
These issues are addressed in the following versions of the Sun
Java Runtime Environment:
* JDK and JRE 6 Update 11
* JDK and JRE 5.0 Update 17
* SDK and JRE 1.4.2_19
* SDK and JRE 1.3.1_24
If you install the latest version of Java, older versions may
remain installed on your computer. If you do not need these older
versions, you can remove them by following Sun's instructions.
Disable Java
Disable Java in your web browser, as described in the Securing Your
Web Browser document. While this does not fix the underlying
vulnerabilities, it does block a common attack vector.
