DESCRIPTION:
Soroush Dalili has discovered a vulnerability in Mozilla Firefox,
which can be exploited by malicious people to disclose potentially
sensitive information.

The vulnerability is caused due to the "window.onerror" handler being
allowed to read the destination URL of a redirection. This can be
exploited to e.g. disclose session-specific query parameters
contained in a target URL by referencing a redirecting site via an
HTML "<script>" tag.

The vulnerability is confirmed in version 3.6.3 and 3.5.9. Other
versions may also be affected.

SOLUTION:
Do not browse untrusted sites while accessing other sites with
potentially sensitive information in the URL.

PROVIDED AND/OR DISCOVERED BY:
Soroush Dalili
