DESCRIPTION:
Sense of Security has discovered a vulnerability in Symfony, which
can be exploited by malicious people to potentially disclose
sensitive information.

The vulnerability is caused due to an error in the XmlEncoder
component when processing certain XML data, which can be exploited to
e.g. disclose local files by sending specially crafted XML data
including external entity references.

The vulnerability is confirmed in version 2.0.10 and reported in

SOLUTION:
