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 ...

K000163699: OpenSSL vulnerability CVE-2026-75803

Security Advisory Description Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the EVPCipher function. Impact summary: Applications calling EVPCipher on ...

RUSTSEC-2026-0337 Poly1305 panics or computes a wrong tag on attacker-chosen messages of 64 bytes or more

Poly1305 in ic-cipher absorbs messages of 64 bytes or more four blocks at a time, summing four products before one reduction. From 0.2.5 to 0.2.19 the reduction kept its carries in 32-bit integers, which four summed products can overflow when the message's bytes are large. This affects Poly1305 a...

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 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...

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

Zephyr's WireGuard implementation in subsys/net/lib/wireguard/wgcrypto.c mishandled keepalive packets. In wgprocessdatamessage, any type-4 transport-data message whose payload was exactly 16 bytes an empty plaintext plus a bare Poly1305 tag, i.e. a keepalive was accepted and returned immediately,...
