Mbed Mbedtls vulnerabilities

CVE-2022-46393 [CRITICAL] CVE-2022-46393: An issue was discovered in Mbed TLS before 2 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-2022-46392 [MEDIUM] CVE-2022-46392: An issue was discovered in Mbed TLS before 2 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-2022-35409 [CRITICAL] CVE-2022-35409: An issue was discovered in Mbed TLS before 2 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 MBE

CVE-2021-43666 [HIGH] CVE-2021-43666: A Denial of Service vulnerability exists in mbed TLS 3 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-2020-36476 [HIGH] CVE-2020-36476: An issue was discovered in Mbed TLS before 2 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-2020-36478 [HIGH] CVE-2020-36478: An issue was discovered in Mbed TLS before 2 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-2020-36475 [HIGH] CVE-2020-36475: An issue was discovered in Mbed TLS before 2 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-2020-36477 [MEDIUM] CVE-2020-36477: An issue was discovered in Mbed TLS before 2 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-byt

CVE-2020-36426 [HIGH] CVE-2020-36426: An issue was discovered in Arm Mbed TLS before 2 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 [HIGH] CVE-2020-36423: An issue was discovered in Arm Mbed TLS before 2 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-2020-36421 [MEDIUM] CVE-2020-36421: An issue was discovered in Arm Mbed TLS before 2 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-2020-36424 [MEDIUM] CVE-2020-36424: An issue was discovered in Arm Mbed TLS before 2 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-2020-36425 [MEDIUM] CVE-2020-36425: An issue was discovered in Arm Mbed TLS before 2 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-2020-36422 [MEDIUM] CVE-2020-36422: An issue was discovered in Arm Mbed TLS before 2 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-2021-24119 [MEDIUM] CVE-2021-24119: In Trusted Firmware Mbed TLS 2 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-2020-16150 [MEDIUM] CVE-2020-16150: A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg 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-2020-10932 [MEDIUM] CVE-2020-10932: An issue was discovered in Arm Mbed TLS before 2 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 200

CVE-2020-10941 [MEDIUM] CVE-2020-10941: Arm Mbed TLS before 2 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-2017-18187 [CRITICAL] mbedtls vulnerabilities mbedtls vulnerabilities It was discovered that mbedtls has a bounds-check bypass through an integer overflow that can be used by an attacked to execute arbitrary code or cause a denial of service. (CVE-2017-18187) It was discovered that mbedtls has a vulnerability where an attacker could execute arbitrary code or cause a denial of service (buffer overflow) via a crafted certificate chain that is mishandled during RSASSA-PSS signature verificati

CVE-2019-18222 [MEDIUM] CVE-2019-18222: The ECDSA signature implementation in ecdsa 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.
