Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Insufficient constraints in Apache's Xalan-Java might allow remote |
| 19 |
attackers to execute arbitrary code and load arbitrary classes. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Xalan-Java is an XSLT processor for transforming XML documents into |
| 25 |
HTML, text, or other XML document types. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-java/xalan < 2.7.2 >= 2.7.2 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The TransformerFactory in Apache Xalan-Java does not properly restrict |
| 39 |
access to certain properties when FEATURE_SECURE_PROCESSING is enabled. |
| 40 |
This can also be exploited via a Java property that is bound to the |
| 41 |
XSLT 1.0 system-property function. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
A remote attacker could inject specially crafted XSLT properties |
| 47 |
resulting in the execution of arbitrary code with the privileges of the |
| 48 |
process. |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known work around at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All Xalan-Java users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=dev-java/xalan-2.7.2" |
| 62 |
|
| 63 |
