Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Groovy is vulnerable to a remote execution of arbitrary code when java |
| 19 |
serialization is used. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
A multi-faceted language for the Java platform |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 dev-java/groovy < 2.4.5 >= 2.4.5 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Groovy's MethodClosure class, in runtime/MethodClosure.java, is |
| 38 |
vulnerable to a crafted serialized object. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
Remote attackers could potentially execute arbitrary code, or cause |
| 44 |
Denial of Service condition |
| 45 |
|
| 46 |
Workaround |
| 47 |
========== |
| 48 |
|
| 49 |
A workaround exists by using a custom security policy file utilizing |
| 50 |
the standard Java security manager, or do not rely on serialization to |
| 51 |
communicate remotely. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All Groovy users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=dev-java/groovy-2.4.5" |
| 60 |
