Description

moz_bug_r_a4 reported that the src attribute of an IMG element loaded in a frame could be changed to a javascript: URI that was able to bypass the protections against cross-site script (XSS) injection. The injected script could steal credentials and financial data, or perform destructive actions on behalf of a logged-in user.

Workaround

Disable JavaScript until you can upgrade to a fixed version.
