Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Sun's and Blackdown's JDK or JRE may allow untrusted applets to elevate |
| 19 |
their privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Sun and Blackdown both provide implementations of the Java Development |
| 25 |
Kit (JDK) and Java Runtime Environment (JRE). |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |

Description |
| 42 |
=========== |
| 43 |
|
| 44 |
Adam Gowdiak discovered multiple vulnerabilities in the Java Runtime |
| 45 |
Environment's Reflection APIs that may allow untrusted applets to |
| 46 |
elevate privileges. |
| 47 |
|
| 48 |
Impact |
| 49 |
====== |
| 50 |
|
| 51 |
A remote attacker could embed a malicious Java applet in a web page and |
| 52 |
entice a victim to view it. This applet can then bypass security |
| 53 |
restrictions and execute any command or access any file with the rights |
| 54 |
of the user running the web browser. |
| 55 |
|
| 56 |
Workaround |
| 57 |
========== |
| 58 |
|
| 59 |
There are no known workarounds at this time. |
| 60 |
|
| 61 |
Resolution |
| 62 |
========== |
| 63 |
|
| 64 |
All Sun JDK users should upgrade to the latest version: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=dev-java/sun-jdk-1.4.2.09" |
| 68 |
|
| 69 |
All Sun JRE users should upgrade to the latest version: |
| 70 |
|
| 71 |
# emerge --sync |
| 72 |
# emerge --ask --oneshot --verbose ">=dev-java/sun-jre-bin-1.4.2.09" |
| 73 |
|
| 74 |
All Blackdown JDK users should upgrade to the latest version: |
| 75 |
|
| 76 |
# emerge --sync |
| 77 |
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jdk-1.4.2.03" |
| 78 |
|
| 79 |
All Blackdown JRE users should upgrade to the latest version: |
| 80 |
|
| 81 |
# emerge --sync |
| 82 |
# emerge --ask --oneshot --verbose ">=dev-java/blackdown-jre-1.4.2.03" |
| 83 |
|
| 84 |
Note to SPARC and PPC users: There is no stable secure Blackdown Java |
| 85 |
for the SPARC or PPC architectures. Affected users on the PPC |
| 86 |
architecture should consider switching to the IBM Java packages |
| 87 |
(ibm-jdk-bin and ibm-jre-bin). Affected users on the SPARC should |
| 88 |
remove the package until a SPARC package is released. |
