/ GitLab Critical Security Release: 16.3.4 and 16.2.7

These versions contain important security fixes, and GitLab strongly recommend that all GitLab installations be upgraded to one of these versions immediately.

In short: A stored XSS vulnerability was discovered in GitLab.com that allowed an attacker to inject HTML in any note, issue denoscription, or wiki page by abusing syntax_highlight_filter.rb. The vulnerability was caused by the lack of proper input sanitization. The attacker could inject a noscript tag by using the base tag and loading the noscript from their own domain, bypassing the CSP. This could lead to the creation of tokens and take over of SSO accounts.

📢. What's the Difference Between Ada and Ric OpenBLD.net? 😡

🌟 Ada - Adaptive DNS: Harmoniously filters malicious content and ensures seamless internet connectivity whenever possible

🚫 Ric - Strict DNS: Blocks many marketing and tracking resources, which may affect access to certain internet content

Curious to learn more? Dive into the details here

I recommend Ada for most OpenBLD.net DNS users. Take care of yourself. Peace out! ✌️

📢🚀 Exciting 2023 Q3 News and Improvements in OpenBLD.net DNS

In first - Big Thanks to the DNS Blocklists project for their significant contribution to "Keep the internet clean" ideology

In this quarter of 2023, I've introduced various enhancements to the OpenBLD.net ecosystem.

🔻 Here's the scoop:

1️⃣ OpenBLD.net now incorporates the DNS Blocklists project into its own DNS filtering mechanisms, ensuring a cleaner internet experience.

2️⃣ Successfully resolved major Apple content delivery issues for Eastern Europe, enhancing DNS delivery experience.

3️⃣ Experience a boost in DNS response speed by approximately 5%. The General pool is now around ~111ms, while Local pools are at ~70ms.

4️⃣ According to Alternativeto, OpenBLD.net stands out as an alternative to Quad9, NextDNS, AdGuard DNS, AhaDNS, and BlahDNS.

And most importantly, OpenBLD.net is your go-to solution for a clean Internet – free from Ads, Tracking, Metrics, Telemetry, Phishing, Malware and all that other "Crap.” without agent installations and add-ins in your browsers.

Embrace yourself and stay focused with the power of clean Internet with https://openbld.net DNS 😎
