openssl: PKCS#12 Files with PBMAC1 Are Accepted with Short HMAC Keys

A flaw was found in OpenSSL. This vulnerability allows a remote attacker to forge PKCS12 Public-Key Cryptography Standards 12 files that use Password-Based Message Authentication Code 1 PBMAC1 with short HMAC Hash-based Message Authentication Code keys. This can lead to a service accepting...

CVE-2026-17508

In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before any password or integrity check could...
