Synopsis
========

A vulnerability has been discovered in Apache Commons Text which could
result in arbitrary code execution.

Background
==========

Apache Commons Text is a library focused on algorithms working on
strings.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/commons-text < 1.10.0 >= 1.10.0

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

Apache Commons Text performs variable interpolation, allowing properties
to be dynamically evaluated and expanded. The standard format for
interpolation is "${prefix:name}", where "prefix" is used to locate an
instance of org.apache.commons.text.lookup.StringLookup that performs
the interpolation. The set of default Lookup instances included
interpolators that could result in arbitrary code execution or contact
with remote servers. These lookups are: - "script" - execute expressions
using the JVM script execution engine (javax.script) - "dns" - resolve
dns records - "url" - load values from urls, including from remote
servers Applications using the interpolation defaults in the affected
versions may be vulnerable to remote code execution or unintentional
contact with remote servers if untrusted configuration values are used.

Impact
======

Crafted input to Apache Commons Text could trigger remote code
execution.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/commons-text-1.10.0"
