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"
