CVE-2021-45450 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2023-11-21 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-2023-43615 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2023-11-09 N/A 7.5 HIGH
Mbed TLS 2.x before 2.28.5 and 3.x before 3.5.0 has a Buffer Overflow.
CVE-2022-46393 2 Arm, Fedoraproject 2 Mbed Tls, Fedora 2023-08-08 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-2022-35409 1 Arm 1 Mbed Tls 2022-07-27 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-2020-36476 2 Arm, Debian 2 Mbed Tls, Debian Linux 2022-07-12 5.0 MEDIUM 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-2020-10932 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-2021-45451 1 Arm 1 Mbed Tls 2022-01-04 5.0 MEDIUM 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-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-2021-44732 1 Arm 1 Mbed Tls 2021-12-29 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.

ARM mbed TLS before 2.1.11, before 2.7.2, and before 2.8.0 has a buffer over-read in ssl_parse_server_key_exchange() that could cause a crash on invalid input.
CVE-2018-9989 2 Arm, Debian 2 Mbed Tls, Debian Linux 2021-11-30 5.0 MEDIUM 7.5 HIGH
ARM mbed TLS before 2.1.11, before 2.7.2, and before 2.8.0 has a buffer over-read in ssl_parse_server_psk_hint() that could cause a crash on invalid input.
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-2020-36475 3 Arm, Debian, Siemens 14 Mbed Tls, Debian Linux, Logo\! Cmr2020 and 11 more 2021-11-26 5.0 MEDIUM 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 2021-11-26 5.0 MEDIUM 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-2020-36477 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-2020-36426 1 Arm 1 Mbed Tls 2021-07-29 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 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-2020-36423 1 Arm 1 Mbed Tls 2021-07-29 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 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-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-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-2018-1000520 1 Arm 1 Mbed Tls 2020-11-05 5.0 MEDIUM 7.5 HIGH
ARM mbedTLS version 2.7.0 and earlier contains a Ciphersuite Allows Incorrectly Signed Certificates vulnerability in mbedtls_ssl_get_verify_result() that can result in ECDSA-signed certificates are accepted, when only RSA-signed ones should be.. This attack appear to be exploitable via Peers negotiate a TLS-ECDH-RSA-* ciphersuite. Any of the peers can then provide an ECDSA-signed certificate, when only an RSA-signed one should be accepted..
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-2018-0488 2 Arm, Debian 2 Mbed Tls, Debian Linux 2020-08-24 7.5 HIGH 9.8 CRITICAL
ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0, when the truncated HMAC extension and CBC are used, allows remote attackers to execute arbitrary code or cause a denial of service (heap corruption) via a crafted application packet within a TLS or DTLS session.
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-2018-0487 2 Arm, Debian 2 Mbed Tls, Debian Linux 2020-02-10 7.5 HIGH 9.8 CRITICAL
ARM mbed TLS before 1.3.22, before 2.1.10, and before 2.7.0 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via a crafted certificate chain that is mishandled during RSASSA-PSS signature verification within a TLS or DTLS session.

CVE-2017-18187 2 Arm, Debian 2 Mbed Tls, Debian Linux 2020-02-10 7.5 HIGH 9.8 CRITICAL
In ARM mbed TLS before 2.7.0, there is a bounds-check bypass through an integer overflow in PSK identity parsing in the ssl_parse_client_psk_identity() function in library/ssl_srv.c.
CVE-2015-8036 5 Arm, Debian, Fedoraproject and 2 more 5 Mbed Tls, Debian Linux, Fedora and 2 more 2019-06-19 6.8 MEDIUM N/A
Heap-based buffer overflow in ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long session ticket name to the session ticket extension, which is not properly handled when creating a ClientHello message to resume a session. NOTE: this identifier was SPLIT from CVE-2015-5291 per ADT3 due to different affected version ranges.
CVE-2015-5291 5 Arm, Debian, Fedoraproject and 2 more 6 Mbed Tls, Debian Linux, Fedora and 3 more 2019-06-19 6.8 MEDIUM N/A
Heap-based buffer overflow in PolarSSL 1.x before 1.2.17 and ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long hostname to the server name indication (SNI) extension, which is not properly handled when creating a ClientHello message. NOTE: this identifier has been SPLIT per ADT3 due to different affected version ranges. See CVE-2015-8036 for the session ticket issue that was introduced in 1.3.0.
CVE-2017-14032 1 Arm 1 Mbed Tls 2017-11-08 6.8 MEDIUM 8.1 HIGH
ARM mbed TLS before 1.3.21 and 2.x before 2.1.9, if optional authentication is configured, allows remote attackers to bypass peer authentication via an X.509 certificate chain with many intermediates. NOTE: although mbed TLS was formerly known as PolarSSL, the releases shipped with the PolarSSL name are not affected.
CVE-2017-2784 1 Arm 1 Mbed Tls 2017-07-01 6.8 MEDIUM 8.1 HIGH
An exploitable free of a stack pointer vulnerability exists in the x509 certificate parsing code of ARM mbed TLS before 1.3.19, 2.x before 2.1.7, and 2.4.x before 2.4.2. A specially crafted x509 certificate, when parsed by mbed TLS library, can cause an invalid free of a stack pointer leading to a potential remote code execution. In order to exploit this vulnerability, an attacker can act as either a client or a server on a network to deliver malicious x509 certificates to vulnerable applications.
