TITLE

plural Yubico Observable inconsistency vulnerabilities in products

Trust: 0.8

sources: JVNDB: JVNDB-2024-007966

DESCRIPTION

Yubico YubiKey 5 Series devices with firmware before 5.7.0 and YubiHSM 2 devices with firmware before 2.4.0 allow an ECDSA secret-key extraction attack (that requires physical access and expensive equipment) in which an electromagnetic side channel is present because of a non-constant-time modular inversion for the Extended Euclidean Algorithm, aka the EUCLEAK issue. Other uses of an Infineon cryptographic library may also be affected. yubikey 5c nfc firmware, YubiKey 5 NFC firmware, yubikey 5c firmware etc. Yubico The product contains an observable inconsistency vulnerability.Information may be obtained
