USN-8418-1: Crypt-SaltedHash vulnerability

Publication date

10 June 2026

Overview

Crypt-SaltedHash incorrectly generated random numbers.


Packages

Details

It was discovered that Crypt-SaltedHash incorrectly generated salts using a
cryptographically weak pseudo-random number generator. An attacker could
possibly use this issue to predict generated salts, leading to a weakening
of cryptographic protections.
