Secunia

Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, or compromise a user's system.

1) An error in the processing of ".url" shortcuts can be exploited to obtain sensitive information from the local cache.

For more information:
SA32192

2) An error in the handling of HTTP redirect requests can be exploited to bypass the same-origin policy and access potential sensitive information stored in images in another domain.

3) An error exists when testing if a Flash module is dynamically unloaded. This can be exploited to dereference memory no longer mapped to the Flash module via an SWF file that dynamically unloads itself from an outside JavaScript function.

4) An error when locking a non-native object can be exploited to cause a crash via a web page assigning a specially crafted value to the "window.__proto__.__proto__" object.

5) An error in the browser engine can be exploited to cause a memory corruption.

6) Two errors in the JavaScript engine can be exploited to cause memory corruptions.

Successful exploitation of vulnerabilities #3-#6 may allow execution of arbitrary code.

7) An error in the browser's restore feature can be exploited to violate the same-origin policy and run arbitrary JavaScript code in the context of another site.

NOTE: The vulnerability can also be exploited to execute arbitrary JavaScript code with chrome privileges.

8) An error in the processing of the "http-index-format" MIME type can be exploited to execute arbitrary code via a specially crafted 200 header line included in an HTTP index response.

9) An error in the DOM constructing code can be exploited to dereference uninitialized memory and potentially execute arbitrary code by modifying certain properties of a file input element before the element has finished initializing.

10) An error in the implementation of the "nsXMLHttpRequest::NotifyEventListeners()" method can be exploited to execute arbitrary JavaScript code in the context of another site.

11) An error when handling the "-moz-binding" CSS property can be exploited to manipulate signed JAR files and execute arbitrary JavaScript code in the context of another site.

12) An error exists when parsing the default XML namespace of an E4X document. This can be exploited to inject arbitrary XML code via a specially crafted namespace containing quote characters.

The vulnerabilities are reported in versions prior to 2.0.0.18.

Solution
Update to version 2.0.0.18.
