Description

A weakness has been discovered in Firefox, which can be exploited by malicious people to disclose system information.

The weakness is caused due to file path information being included in certain exceptions being thrown by the browser. This can e.g. be exploited to disclose the full installation path by calling the "window.sidebar.addSearchEngine()" JavaScript function with invalid parameters.

This may reportedly also be exploited to disclose the full path to the user's profile via errors thrown in installed extensions.

The weakness has been confirmed in version 1.5.0.3. Other versions may also be affected.


Solution
Update to version 1.5.0.5.

Provided and/or discovered by
Originally discovered by Martin Hassman and reported to public mailing lists by milw0rm.
