Ubuntu 24.04 LTS pbkdf2 Important Signature Spoofing Risk USN-8452-1

pbkdf2 could be made to generate predictable cryptographic keys if it received specially crafted input.. ========================================================================== Ubuntu Security Notice USN-8452-1 June 18, 2026 node-pbkdf2 vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 24.04 LTS - Ubuntu 22.04 LTS - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS Summary: pbkdf2 could be made to generate predictable cryptographic keys if it received specially crafted input. Software Description: - node-pbkdf2: PBKDF2 with any supported hashing algorithm in Node Details: Nikita Skovoroda discovered that pbkdf2 did not properly validate certain algorithm names. An attacker could possibly use this issue to generate predictable cryptographic keys, resulting in signature spoofing. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 24.04 LTS node-pbkdf2 3.1.2-3ubuntu0.1~esm1 Available with Ubuntu Pro Ubuntu 22.04 LTS node-pbkdf2 3.1.2-2ubuntu0.1~esm1 Available with Ubuntu Pro Ubuntu 20.04 LTS node-pbkdf2 3.0.16-1ubuntu0.1~esm1 Available with Ubuntu Pro Ubuntu 18.04 LTS node-pbkdf2 3.0.14-2ubuntu0.1~esm1 Available with Ubuntu Pro In general, a standard system update will make all the necessary changes.
