DESCRIPTION:
A vulnerability has been reported in Firefox, which can be exploited
by malicious people to disclose sensitive information.
The vulnerability is caused due to an error when processing .url
shortcuts in HTML elements. This can be exploited to disclose
potentially sensitive information from the cache.
Successful exploitation requires that a user is e.g. tricked into
opening an HTML page from a local directory or a RAR archive
containing .url files.
The vulnerability is reported in version 3.0.3. Other versions may
also be affected.
SOLUTION:
Do not open HTML files from untrusted sources.
