Security

Cross-platform apps built with the popular Flutter toolkit can now benefit from Dependabot alerts.

Dependabot alerts can give you the ability to secure your project by keeping dependency-based vulnerabilities out of your code. Here are some tips to more efficiently prioritize and take action on your alerts, so you can get back to building.

We’re taking a look at two commonly-used security tools and detailing how they can help secure your projects.

Supply chain attacks exploit our implicit trust of open source to hurt developers and our customers. Read our proposal for how npm will significantly reduce supply chain attacks by signing packages with Sigstore.

In this post I’ll exploit CVE-2022-20186, a vulnerability in the Arm Mali GPU kernel driver and use it to gain arbitrary kernel memory access from an untrusted app on a Pixel 6. This then allows me to gain root and disable SELinux. This vulnerability highlights the strong primitives that an attacker may gain by exploiting errors in the memory management code of GPU drivers.

New Actions from Anchore, NowSecure, SBT, and Trivy are now available to create a more comprehensive GitHub Dependency Graph.

In this post I’ll exploit CVE-2022-1134, a type confusion in Chrome that I reported in March 2022, which allows remote code execution (RCE) in the renderer sandbox of Chrome by a single visit to a malicious site. I’ll also look at some past vulnerabilities of this type and some implementation details of inline cache in V8, the JavaScript engine of Chrome.

We’re excited to announce that the GitHub Advisory Database now includes curated security advisories on Erlang, Elixir, and more.

Expand the completeness of your dependency graph by using the dependency submission API, which will create more comprehensive alerts on supply chain vulnerabilities

In this post I’ll exploit CVE-2022-22057, a use-after-free in the Qualcomm gpu kernel driver, to gain root and disable SELinux from the untrusted app sandbox on a Samsung Z flip 3. I’ll look at various mitigations that are implemented on modern Android devices and how they affect the exploit.

To combat the prevalence of malware in the open source ecosystem, GitHub now publishes malware occurrences in the GitHub Advisory Database. These advisories power Dependabot alerts and remain forever free and usable by the community.

The Rust community can now discover, report, and prevent security vulnerabilities.

It was another record year for our Security Bug Bounty program. We’re excited to highlight some achievements we’ve made together with the bounty community from 2021!

We’re taking a look at some of the most common security vulnerabilities and detailing how developers can best protect themselves.
