Tablib: Arbitrary command execution

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.

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"
