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 |
