Where:

From remote

Impact:

Security Bypass, Cross Site Scripting, System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to conduct cross-site scripting attacks, bypass certain security restrictions, or compromise a user's system.

1) An error exists when handling out-of-memory conditions. This can be exploited to trigger a memory corruption and execute arbitrary code via a specially crafted web page.

2) Multiple errors in the browser engine can be exploited to corrupt memory and potentially execute arbitrary code.

3) An error in the implementation of Web Worker array data types when processing posted messages can be exploited to corrupt memory and potentially execute arbitrary code.

4) An error exists in the implementation of the "showModalDialog()" function. This can be exploited to potentially execute arbitrary JavaScript code in the context of a domain calling the affected function with external parameters.

5) An error exists when processing SVG documents served with a Content-Type of "application/octet-stream". This can be exploited to execute arbitrary JavaScript code in the context of a domain hosting the SVG document.

6) Multiple errors in the browse engine can be exploited to corrupt memory and potentially execute arbitrary code.

7) An error related to the implementation of the "addEventListener()" and "setTimeout()" methods can be exploited to bypass the same-origin policy.

This is related to vulnerability #3 in:
SA26095

8) An error in the processing of stylesheets used in XUL documents can be exploited to pollute the XUL cache and change browser style attributes.

9) An error related to the XMLHttpRequestSpy object can be exploited to execute arbitrary JavaScript code with chrome privileges.

The vulnerabilities are reported in versions prior to 3.5.8 and 3.0.18.


Solution:
Update to version 3.0.18 or 3.5.8.
