Synopsis
========

BeanShell is vulnerable to the remote execution of arbitrary code via
Java serialization or XStream from an untrusted source.

Background
==========

BeanShell is a small, free, embeddable Java source interpreter with
object scripting language features, written in Java.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/bsh < 2.0_beta6 >= 2.0_beta6

Description
===========

An application that includes BeanShell on the classpath may be
vulnerable if another part of the application uses Java serialization
or XStream to deserialize data from an untrusted source.

Impact
======

Remote attackers could execute arbitrary code including shell commands.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All BeanShell users should upgrade to the latest version:

# emerge --sync
# emerge --ask --verbose --oneshot ">=dev-java/bsh-2.0_beta6"

References
