CVE-2020-10932 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2022-05-03 1.9 LOW 5.5 MEDIUM
An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by (1) reconstructing the projective coordinate of the result of scalar multiplication by exploiting side channels in the conversion to affine coordinates; (2) using an attack described by Naccache, Smart, and Stern in 2003 to recover a few bits of the ephemeral scalar from those projective coordinates via several measurements; and (3) using a lattice attack to get from there to the long-term ECDSA private key used for the signatures. Typically an attacker would have sufficient access when attacking an SGX enclave and controlling the untrusted OS.
CVE-2019-18222 2 Arm, Fedoraproject 3 Mbed Crypto, Mbed Tls, Fedora 2022-01-01 1.9 LOW 4.7 MEDIUM
The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks.
CVE-2021-24119 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2021-11-28 4.0 MEDIUM 4.9 MEDIUM
In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability in base64 PEM file decoding allows system-level (administrator) attackers to obtain information about secret RSA keys via a controlled-channel and side-channel attack on software running in isolated environments that can be single stepped, especially Intel SGX.
CVE-2020-36477 1 Arm 1 Mbed Tls 2021-08-26 4.3 MEDIUM 5.9 MEDIUM
An issue was discovered in Mbed TLS before 2.24.0. The verification of X.509 certificates when matching the expected common name (the cn argument of mbedtls_x509_crt_verify) with the actual certificate name is mishandled: when the subjecAltName extension is present, the expected name is compared to any name in that extension regardless of its type. This means that an attacker could impersonate a 4-byte or 16-byte domain by getting a certificate for the corresponding IPv4 or IPv6 address (this would require the attacker to control that IP address, though).
CVE-2020-36425 1 Arm 1 Mbed Tls 2021-07-29 4.3 MEDIUM 5.3 MEDIUM
An issue was discovered in Arm Mbed TLS before 2.24.0. It incorrectly uses a revocationDate check when deciding whether to honor certificate revocation via a CRL. In some situations, an attacker can exploit this by changing the local clock.
CVE-2020-36424 1 Arm 1 Mbed Tls 2021-07-29 1.9 LOW 4.7 MEDIUM
An issue was discovered in Arm Mbed TLS before 2.24.0. An attacker can recover a private key (for RSA or static Diffie-Hellman) via a side-channel attack against generation of base blinding/unblinding values.
CVE-2020-36422 1 Arm 1 Mbed Tls 2021-07-29 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Arm Mbed TLS before 2.23.0. A side channel allows recovery of an ECC private key, related to mbedtls_ecp_check_pub_priv, mbedtls_pk_parse_key, mbedtls_pk_parse_keyfile, mbedtls_ecp_mul, and mbedtls_ecp_mul_restartable.
CVE-2020-36421 1 Arm 1 Mbed Tls 2021-07-29 5.0 MEDIUM 5.3 MEDIUM
An issue was discovered in Arm Mbed TLS before 2.23.0. Because of a side channel in modular exponentiation, an RSA private key used in a secure enclave could be disclosed.
CVE-2019-16910 2 Arm, Fedoraproject 3 Mbed Crypto, Mbed Tls, Fedora 2021-07-21 2.6 LOW 5.3 MEDIUM
Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when deterministic ECDSA is enabled, use an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times. (For Mbed TLS, the fix is also available in versions 2.7.12 and 2.16.3.)
CVE-2020-10941 2 Arm, Fedoraproject 3 Mbed Crypto, Mbed Tls, Fedora 2021-07-21 4.3 MEDIUM 5.9 MEDIUM
Arm Mbed TLS before 2.16.5 allows attackers to obtain sensitive information (an RSA private key) by measuring cache usage during an import.
CVE-2020-16150 1 Arm 1 Mbed Tls 2020-09-25 2.1 LOW 5.5 MEDIUM
A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length.
CVE-2018-19608 1 Arm 1 Mbed Tls 2020-08-24 1.9 LOW 4.7 MEDIUM
Arm Mbed TLS before 2.14.1, before 2.7.8, and before 2.1.17 allows a local unprivileged attacker to recover the plaintext of RSA decryption, which is used in RSA-without-(EC)DH(E) cipher suites.
CVE-2018-0497 2 Arm, Debian 2 Mbed Tls, Debian Linux 2020-02-10 4.3 MEDIUM 5.9 MEDIUM
ARM mbed TLS before 2.12.0, before 2.7.5, and before 2.1.14 allows remote attackers to achieve partial plaintext recovery (for a CBC based ciphersuite) via a timing-based side-channel attack. This vulnerability exists because of an incorrect fix (with a wrong SHA-384 calculation) for CVE-2013-0169.
CVE-2018-0498 2 Arm, Debian 2 Mbed Tls, Debian Linux 2020-02-10 1.9 LOW 4.7 MEDIUM
ARM mbed TLS before 2.12.0, before 2.7.5, and before 2.1.14 allows local users to achieve partial plaintext recovery (for a CBC based ciphersuite) via a cache-based side-channel attack.
