Description


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

1) A boundary error in the processing of hyperlinks can be exploited to cause a stack-based buffer overflow via a specially crafted UTF-8 hyperlink URL.

Successful exploitation may allow execution of arbitrary code.

2) An error in the implementation of the same-origin check in "nsXMLDocument::OnChannelRedirect()" can be exploited to execute arbitrary script code in the context of a different website.

3) Multiple errors in "feedWriter" can be exploited to execute arbitrary script code with Chrome privileges.

4) An error in the JavaScript move and resize functionality can be exploited to trick the user into clicking an unintended button and e.g. download a malicious file.

5) Multiple errors can be exploited to pollute "XPCNativeWrappers" and run arbitrary script code with Chrome privileges.

6) Multiple errors in "XSLT" and "document.loadBindingDocument()" while creating documents can be exploited to run arbitrary script code with Chrome privileges.

7) Multiple errors in the layout and JavaScript engines can be exploited to corrupt memory.

Successful exploitation of the vulnerability may allow execution of arbitrary code.

8) An error in the processing of BOM characters included in JavaScript code can be exploited to potentially bypass script filters and facilitate cross-site scripting attacks.

9) An error exists in the HTML parser when processing low surrogate HTML-escaped characters can be exploited to potentially bypass script filters and facilitate cross-site scripting.

10) Multiple errors in the implementation of the "resource:" protocol can be exploited to perform directory traversal attacks and disclose sensitive information.

11) An error in the XBM decoder can be exploited to read data from uninitialized memory locations.

The vulnerabilities are reported in versions prior to 2.0.0.17.


Solution:
Update to version 2.0.0.17.
