GHSA-CMR8-5W4C-44V8 Fastly Compute@Edge JS Runtime has fixed random number seed during compilation

Impact Math.random and crypto.getRandomValues methods failed to use sufficiently random values. The initial value to seed the CSPRNG cryptographically secure pseudorandom number generator was baked-in to the final WebAssembly module meaning the sequence of numbers generated was predictable for th...

Node.js: Weak randomness in WebCrypto keygen

https://github.com/nodejs/node/pull/35093 introduced a call to EntropySource in SecretKeyGenTraits::DoKeyGen in src/crypto/cryptokeygen.cc. There are two problems with this: 1. It does not check the return value, it assumes EntropySource always succeeds, but it can and sometimes will fail. 2. The...

Use of Insufficiently Random Values

An issue was discovered in supplementary Go cryptography libraries, aka golang-googlecode-go-crypto, before 2019-03-20. A flaw was found in the amd64 implementation of golang.org/x/crypto/salsa20 and golang.org/x/crypto/salsa20/salsa. If more than 256 GiB of keystream is generated, or if the...

Path traversal

keypair is a a RSA PEM key generator written in javascript. keypair implements a lot of cryptographic primitives on its own or by borrowing from other libraries where possible, including node-forge. An issue was discovered where this library was generating identical RSA keys used in SSH. This wou...

A Critical Random Number Generator Flaw Affects Billions of IoT Devices

A critical vulnerability has been disclosed in hardware random number generators used in billions of Internet of Things IoT devices whereby it fails to properly generate random numbers, thus undermining their security and putting them at risk of attacks. "It turns out that these 'randomly' chosen...

Debian DLA-2454-1 : rclone security update

golang-go.crypto was recently updated with a fix for CVE-2019-11840. This in turn requires all packages that use the affected code to be recompiled in order to pick up the security fix. CVE-2019-11840 An issue was discovered in supplementary Go cryptography libraries, aka...

The Linux CSPRNG Is Now Good!

Oceans of ink and hours on stage have been spent to convince the world that the best random number generator is /dev/urandom, the kernel one. And it is, and its always been. However, an uncomfortable truth was that the Linux CSPRNG really could have been better than it was. Userspace CSPRNGs...

Uses insecure CSPRNG (openssl_random_pseudo_bytes())

It's not fork safe In most versions of PHP, it lies about being secure And today I learned that OpenSSL, by default i.e. unchangable from PHP land uses MD5 as a CSPRNG thanks @atoponce I'm stuck between several possible avenues: Release a new version v1.3.0 or most likely v2.0.0 that doesn't rely...
