External Block Generator Code path Vulnerabilities

Prysm version 4.0.3 fixes a critical external block generator code path vulnerability. Block generator determines which validator will generate the next block and adds it to the Ethereum blockchain.

Prysm version 4.0.3 addresses this critical vulnerability with upgrades to its external block generator code path.

Key Manager Vulnerabilities

Prysm version 4.0.3 also comes with upgrades addressing key manager vulnerabilities. Key manager files are significant components of the Ethereum network keys; they are used to control the validators’ private keys, responsible for signing blocks added to the Ethereum blockchain. A bug in the key manager module could have severe consequences for the Ethereum network’s security. Several members of the Ethereum community have worked hard, resulting in important security patches on the key manager vulnerability.
