# Security digest: October 26, 2010

1 editorial brief.

## Take stock

- Most can relax: Firefox CVE-2010-3765: 2010 Zero-Day Added to KEV in 2025 . Owners of legacy machines, kiosks or frozen images that still run Firefox 3.5/3.6, Thunderbird 3.0/3.1 or SeaMonkey 2.0 with JavaScript enabled.
- None of it touches your stack? Then there is nothing to do today. That is a result, not a failure to read carefully.
