keeper

keeper Keeper is a cryptographic secret store for Go. It encrypts arbitrary byte payloads at rest using Argon2id key derivation and XChaCha20-Poly1305 default authenticated encryption, and stores them in an embedded bbolt database. It ships as three things you can use independently: A Go library ...

CVE-2026-15890: Reusing a Nonce, Key Pair in Encryption

The default AEAD nonce provider for the PSA Internal Trusted Storage transform module, securestorageitstransformaeadgetnonce in subsys/securestorage/src/its/transform/aeadget.c, stores its nonce counter in unsynchronized function-local static variables snonce and snonceinitialized. Every ITS writ...

Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...

Astra Linux – Vulnerabilities in paramiko, libssh, libssh2, erlang, openssh

The SSH transport protocol, with certain OpenSSH extensions, found in OpenSSH versions prior to 9.6 and other products, allows remote attackers to bypass integrity checks. As a result, some packets may be omitted from the extension negotiation message. Consequently, the client and server may end ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

openssl: openssl: AEAD forgeries possible with empty ciphertext in EVP_Cipher()

A flaw in OpenSSL causes EVPCipher to skip AEAD tag verification for ChaCha20-Poly1305 and AES-OCB ciphers when decrypting empty ciphertexts. This allows remote attackers to submit forged messages that affected applications incorrectly accept as valid...

CVE-2026-13735
