Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Java Web Start JNLP files can be abused to evade sandbox restriction |
| 19 |
and execute arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Sun provides implementations of Java Development Kits (JDK) and Java |
| 25 |
Runtime Environments (JRE). These implementations provide the Java Web |
| 26 |
Start technology that can be used for easy client-side deployment of |
| 27 |
Java applications. |

Description |
| 44 |
=========== |
| 45 |
|
| 46 |
Jouko Pynnonen discovered that Java Web Start contains a vulnerability |
| 47 |
in the way it handles property tags in JNLP files. |
| 48 |
|
| 49 |
Impact |
| 50 |
====== |
| 51 |
|
| 52 |
By enticing a user to open a malicious JNLP file, a remote attacker |
| 53 |
could pass command line arguments to the Java Virtual machine, which |
| 54 |
can be used to bypass the Java "sandbox" and to execute arbitrary code |
| 55 |
with the permissions of the user running the application. |
| 56 |
|
| 57 |
Workaround |
| 58 |
========== |
| 59 |
|
| 60 |
There is no known workaround at this time. |
| 61 |
|
| 62 |
Resolution |
| 63 |
========== |
| 64 |
|
| 65 |
All Sun JDK users should upgrade to the latest version: |
| 66 |
|
| 67 |
# emerge --sync |
| 68 |
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.07" |
| 69 |
|
| 70 |
All Sun JRE users should upgrade to the latest version: |
| 71 |
|
| 72 |
# emerge --sync |
| 73 |
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.07" |
