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"
