- 1. Solana vulnerability ELI5Often with crypto currencies, things are so complex that it can be difficult to unravel exactly what a vulnerability is, and how it's exploited - especially to those of us who are not really into crypto. Here's a simple Reddit post that plainly describes a recently vuln on Solana
- 2. Openssl bug could result in client DOSA bug in function for doing modular square roots in openssl could result in a client-side DOS for elliptic curve public keys crafted with invalid parameters. Of note, this function is used to provide functionality for supporting elliptic curve keys of arbitrary length.
- 3. Security for package maintainersWe talk about open source supply chain security, but here's a post talking through what that means to a maintainer of python packages
- 4. How to burp goodAt least for me, when I use Burp Suite I'm almost always just using a tiny fraction of it's capabilities. While several years old, here's a post with some good suggestions on how to get more out of Burp. (h/t tl;drsec)
- 5. Peacenotwar module brings not-peace to vue communityA developer decided to protest the war in Ukraine by modifying a npm package he maintains to target systems in Russia that attempt to use the package. What can node do about this? Should maintainers lose all privileges when they pull a stunt like this?
- 6. Cr8escape vulnerability in cri-o comes from new functionalityIn version 1.19 of cri-o - one of the container runtimes used with kubernetes - functionality was added to allow a user to pass sysctl settings when creating a container. With this feature, any sysctl options were taken without filtering or validation. As a POC, the researchers show modifying the kernel configuration on what to do during a core dump (run malicious program).
