Synopsis
========

A vulnerability in Tablib might allow remote attackers to execute
arbitrary python commands.

Background
==========

Tablib is an MIT Licensed format-agnostic tabular dataset library,
written in Python. It allows you to import, export, and manipulate
tabular data sets.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-python/tablib            < 0.12.1                  >= 0.12.1 

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

A vulnerability was discovered in Tablib's Databook loading
functionality, due to improper input validation.

Impact
======

A remote attacker, by enticing the user to process a specially crafted
Databook via YAML, could possibly execute arbitrary python commands
with the privilege of the process.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Tablib users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-python/tablib-0.12.1"
