CVE-2026-34155

RAUC controls the update process on embedded Linux systems. Prior to version 1.15.2, RAUC bundles using the 'plain' format exceeding a payload size of 2 GiB cause an integer overflow which results in a signature which covers only the first few bytes of the payload. Given such a bundle with a...

CGGMP21 presignatures can be used in the way that significantly reduces security

This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously you could generate a presignature, and then choose a HD derivation path while issuing a partial signature via Presignature::setderivationpath,...

Yubico YubiKey 安全漏洞

Yubico YubiKey is a hardware authentication device from the Swedish company Yubico. A security vulnerability exists in Yubico YubiKey versions 5.4.1 through 5.7.3, which stems from an incorrect implementation of the FIDO CTAP PIN/UV Auth Protocol Two, which could lead to partial signature...
