Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Sun's Java Development Kit (JDK) and Java Runtime Environment (JRE) do |
| 19 |
not adequately constrain applets from privilege escalation and |
| 20 |
arbitrary code execution. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Sun's JDK and JRE provide interpreters for Java Applets in a sandboxed |
| 26 |
environment. These implementations provide the Java Web Start |
| 27 |
technology that can be used for easy client-side deployment of Java |
| 28 |
applications. |
| 29 |

Description |
| 43 |
=========== |
| 44 |
|
| 45 |
Applets executed using JRE or JDK can use "reflection" APIs functions |
| 46 |
to elevate its privileges beyond the sandbox restrictions. Adam Gowdiak |
| 47 |
discovered five vulnerabilities that use this method for privilege |
| 48 |
escalation. Two more vulnerabilities were discovered by the vendor. |
| 49 |
Peter Csepely discovered that Web Start Java applications also can an |
| 50 |
escalate their privileges. |
| 51 |
|
| 52 |
Impact |
| 53 |
====== |
| 54 |
|
| 55 |
A malicious Java applet can bypass Java sandbox restrictions and hence |
| 56 |
access local files, connect to arbitrary network locations and execute |
| 57 |
arbitrary code on the user's machine. Java Web Start applications are |
| 58 |
affected likewise. |
| 59 |
|
| 60 |
Workaround |
| 61 |
========== |
| 62 |
|
| 63 |
Select another Java implementation using java-config. |
| 64 |
|
| 65 |
Resolution |
| 66 |
========== |
| 67 |
|
| 68 |
All Sun JDK users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.10" |
| 72 |
|
| 73 |
All Sun JRE users should upgrade to the latest version: |
| 74 |
|
| 75 |
# emerge --sync |
| 76 |
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.10" |
| 77 |
