## Description

The theme implementation in Moodle 2.0.x before 2.0.4 and 2.1.x before
2.1.1 triggers duplicate caching of Cascading Style Sheets (CSS) and
JavaScript content, which allows remote attackers to bypass intended access
restrictions and write to an operating-system temporary directory via
unspecified vectors.
