CVE-2022-35409 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-03-03 N/A 9.1 CRITICAL
An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server that causes a heap-based buffer over-read of up to 255 bytes. This can cause a server crash or possibly information disclosure based on error responses. Affected configurations have MBEDTLS_SSL_DTLS_CLIENT_PORT_REUSE enabled and MBEDTLS_SSL_IN_CONTENT_LEN less than a threshold that depends on the configuration: 258 bytes if using mbedtls_ssl_cookie_check, and possibly up to 571 bytes with a custom cookie check function.
CVE-2020-10932 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2023-03-03 1.9 LOW 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-2019-18222 3 Arm, Debian, Fedoraproject 4 Mbed Crypto, Mbed Tls, Debian Linux and 1 more 2023-03-03 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-2019-16910 3 Arm, Debian, Fedoraproject 4 Mbed Crypto, Mbed Tls, Debian Linux and 1 more 2023-03-03 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-2022-46392 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2023-03-01 N/A 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.
CVE-2022-46393 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2023-03-01 N/A 9.8 CRITICAL
An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. There is a potential heap-based buffer overflow and heap-based buffer over-read in DTLS if MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX.
CVE-2020-16150 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2023-02-27 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-2021-24119 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2023-02-23 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-2020-10941 3 Arm, Debian, Fedoraproject 4 Mbed Crypto, Mbed Tls, Debian Linux and 1 more 2023-02-23 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-2021-44732 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-02-23 7.5 HIGH 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 2023-02-02 5.0 MEDIUM 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 2023-01-27 N/A 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-2021-45450 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2023-01-13 5.0 MEDIUM 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-2020-36477 1 Arm 1 Mbed Tls 2023-01-13 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-2020-36426 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-01-11 5.0 MEDIUM 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-2020-36425 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-01-11 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 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-01-11 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-2020-36423 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-01-11 5.0 MEDIUM 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 2023-01-11 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 2 Arm, Debian 2 Mbed Tls, Debian Linux 2023-01-11 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.
