Synopsis
========

Apache Commons Collections unsafely deserializes untrusted input,
potentially resulting in arbitrary code execution.

Background
==========

Apache Commons Collections extends the JCF classes with new interfaces,
implementations and utilities.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

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

Some classes in the Apache Commons Collections functor package
deserialized potentially untrusted input by default.

Impact
======

Deserializing untrusted input using Apache Commons Collections could
result in remote code execution.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Apache Commons Collections users should upgrade to the latest
version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-java/commons-collections-3.2.2"
