Summary:

opened a malicious website.

Software Description:
– firefox: Mozilla Open Source web browser

Details:

Multiple security issues were discovered in Firefox. If a user were

potentially exploit these to cause a denial of service, obtain sensitive
information, bypass permission prompts, or execute arbitrary code.

not terminating with built-in roots were silently rejected. This could
