Synopsis
========
A vulnerability has been discovered in Commons-BeanUtils, which can lead
to execution of arbitrary code.
Background
==========
Commons-beanutils provides easy-to-use wrappers around Reflection and
Introspection APIs
Affected packages
=================
Package Vulnerable Unaffected
-------------------------- ------------ ------------
dev-java/commons-beanutils < 1.11.0 >= 1.11.0
Description
===========
Multiple vulnerabilities have been discovered in Commons-BeanUtils.
Please review the CVE identifiers referenced below for details.
Impact
======
A special BeanIntrospector class was added in version 1.9.2. This can be
used to stop attackers from using the declared class property of Java
enum objects to get access to the classloader. However this protection
was not enabled by default. PropertyUtilsBean (and consequently
BeanUtilsBean) now disallows declared class level property access by
default.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Commons-BeanUtils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/commons-beanutils-1.11.0"
