Recent Arm Mbed Tls Security Vulnerabilities
An issue was discovered in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2
CVE-2024-23170
5.5 - Medium
- January 31, 2024
An issue was discovered in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2. There was a timing side channel in RSA private operations. This side channel could be sufficient for a local attacker to recover the plaintext. It requires the attacker to send a large number of messages for decryption, as described in "Everlasting ROBOT: the Marvin Attack" by Hubert Kario.

CVE-2022-46393
9.8 - Critical
- December 15, 2022

Out-of-bounds Read
An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0
CVE-2022-46392
5.3 - Medium
- December 15, 2022

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.
Side Channel Attack
An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0
CVE-2022-35409
9.1 - Critical
- July 15, 2022
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-2021-44732
9.8 - Critical
- December 20, 2021

Double-free
An issue was discovered in Mbed TLS before 2.24.0
CVE-2020-36477
5.9 - Medium
- August 23, 2021
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).
Improper Certificate Validation
An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS)
CVE-2020-36478
7.5 - High
- August 23, 2021
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.
Improper Certificate Validation
An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS)
CVE-2020-36475
7.5 - High
- August 23, 2021
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.
Incorrect Calculation of Buffer Size
An issue was discovered in Mbed TLS before 2.24.0 (and before 2.16.8 LTS and before 2.7.17 LTS)
CVE-2020-36476
7.5 - High
- August 23, 2021
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.

5.3 - Medium
- July 19, 2021

Side Channel Attack
An issue was discovered in Arm Mbed TLS before 2.23.0
CVE-2020-36423
7.5 - High
- July 19, 2021

Cleartext Transmission of Sensitive Information
An issue was discovered in Arm Mbed TLS before 2.24.0
CVE-2020-36424
4.7 - Medium
- July 19, 2021

5.3 - Medium
- July 19, 2021

CVE-2020-36426
7.5 - High

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
CVE-2021-24119
4.9 - Medium
- July 14, 2021
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.
Side Channel Attack
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
CVE-2020-16150
5.5 - Medium
- September 02, 2020
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.
Side Channel Attack
An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15
CVE-2020-10932
4.7 - Medium
- April 15, 2020
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
4.7 - Medium
- January 23, 2020
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.

5.3 - Medium
- September 26, 2019
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.)
Arm Mbed TLS before 2.14.1, before 2.7.8, and before 2.1.17
