| CVE-2020-36477 | 1 Arm | 1 Mbed Tls | 2024-08-04 | 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-2020-36476 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 7.5 High |
| An issue was discovered in Mbed TLS before 2.24.0 (and before 2.16.8 LTS and before 2.7.17 LTS). There is missing zeroization of plaintext buffers in mbedtls_ssl_read to erase unused application data from memory. | ||||
| CVE-2020-36475 | 3 Arm, Debian, Siemens | 14 Mbed Tls, Debian Linux, Logo\! Cmr2020 and 11 more | 2024-08-04 | 7.5 High |
| An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). The calculations performed by mbedtls_mpi_exp_mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs. | ||||
| CVE-2020-36478 | 3 Arm, Debian, Siemens | 14 Mbed Tls, Debian Linux, Logo\! Cmr2020 and 11 more | 2024-08-04 | 7.5 High |
| An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS). A NULL algorithm parameters entry looks identical to an array of REAL (size zero) and thus the certificate is considered valid. However, if the parameters do not match in any way, then the certificate should be considered invalid. | ||||
| CVE-2020-36424 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 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-2020-36426 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 7.5 High |
| An issue was discovered in Arm Mbed TLS before 2.24.0. mbedtls_x509_crl_parse_der has a buffer over-read (of one byte). | ||||
| CVE-2020-36423 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 7.5 High |
| An issue was discovered in Arm Mbed TLS before 2.23.0. A remote attacker can recover plaintext because a certain Lucky 13 countermeasure doesn't properly consider the case of a hardware accelerator. | ||||
| CVE-2020-36422 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 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 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 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-2020-36425 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 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-2020-16150 | 3 Arm, Debian, Fedoraproject | 3 Mbed Tls, Debian Linux, Fedora | 2024-08-04 | 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-2020-10941 | 3 Arm, Debian, Fedoraproject | 4 Mbed Crypto, Mbed Tls, Debian Linux and 1 more | 2024-08-04 | 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-2020-10932 | 3 Arm, Debian, Fedoraproject | 3 Mbed Tls, Debian Linux, Fedora | 2024-08-04 | 4.7 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-2021-45450 | 2 Arm, Fedoraproject | 2 Mbed Tls, Fedora | 2024-08-04 | 7.5 High |
| In Mbed TLS before 2.28.0 and 3.x before 3.1.0, psa_cipher_generate_iv and psa_cipher_encrypt allow policy bypass or oracle-based decryption when the output buffer is at memory locations accessible to an untrusted application. | ||||
| CVE-2021-45451 | 2 Arm, Fedoraproject | 2 Mbed Tls, Fedora | 2024-08-04 | 7.5 High |
| In Mbed TLS before 3.1.0, psa_aead_generate_nonce allows policy bypass or oracle-based decryption when the output buffer is at memory locations accessible to an untrusted application. | ||||
| CVE-2021-44732 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 9.8 Critical |
| Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure. | ||||
| CVE-2021-43666 | 2 Arm, Debian | 2 Mbed Tls, Debian Linux | 2024-08-04 | 7.5 High |
| A Denial of Service vulnerability exists in mbed TLS 3.0.0 and earlier in the mbedtls_pkcs12_derivation function when an input password's length is 0. | ||||
| CVE-2021-36647 | 1 Arm | 1 Mbed Tls | 2024-08-04 | 4.7 Medium |
| Use of a Broken or Risky Cryptographic Algorithm in the function mbedtls_mpi_exp_mod() in lignum.c in Mbed TLS Mbed TLS all versions before 3.0.0, 2.27.0 or 2.16.11 allows attackers with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) to recover the private keys used in RSA. | ||||
| CVE-2021-24119 | 3 Arm, Debian, Fedoraproject | 3 Mbed Tls, Debian Linux, Fedora | 2024-08-03 | 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-2022-46392 | 2 Arm, Fedoraproject | 2 Mbed Tls, Fedora | 2024-08-03 | 5.3 Medium |
| An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. An adversary with access to precise enough information about memory accesses (typically, an untrusted operating system attacking a secure enclave) can recover an RSA private key after observing the victim performing a single private-key operation, if the window size (MBEDTLS_MPI_WINDOW_SIZE) used for the exponentiation is 3 or smaller. | ||||
