UBUNTU-CVE-2026-45446

Issue summary: The implementations of AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 mishandle the authentication of AAD Additional Authenticated Data with an empty ciphertext allowing a forgery of such messages. Impact summary: An attacker can forge empty messages with arbitrary AAD to the victim's...

Incorrect Tag Processing for Empty Messages in AES-GCM-SIV and AES-SIV modes

Issue summary: The implementations of AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 mishandle the authentication of AAD Additional Authenticated Data with an empty ciphertext allowing a forgery of such messages. Impact summary: An attacker can forge empty messages with arbitrary AAD to the victim’s...

CVE-2026-25998 strongMan vulnerable to private credential recovery due to key and counter reuse

strongMan is a management interface for strongSwan, an OpenSource IPsec-based VPN. When storing credentials in the database private keys, EAP secrets, strongMan encrypts the corresponding database fields. So far it used AES in CTR mode with a global database key. Together with an initialization...

CVE-2026-25998: Reusing a Nonce, Key Pair in Encryption

strongMan is a management interface for strongSwan, an OpenSource IPsec-based VPN. When storing credentials in the database private keys, EAP secrets, strongMan encrypts the corresponding database fields. So far it used AES in CTR mode with a global database key. Together with an initialization...

AEADs/aes-gcm: Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Summary In the AES GCM implementation of decryptinplacedetached, the decrypted ciphertext i.e. the correct plaintext is exposed even if tag verification fails. Impact If a program using the aes-gcm crate's decryptinplace APIs accesses the buffer after decryption failure, it will contain a...

project abandoned; migrate to the `aes-siv` crate

The Miscreant project has been abandoned and archived. The Rust implementation has been adapted into the new aes-siv crate which implements both the AES-CMAC-SIV and AES-PMAC-SIV constructions: Please migrate to the aes-siv crate. Alternatively see the aes-gcm-siv crate for a newer, faster...
