SUSE CVE-2020-36477

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 mbedtlsx509crtverify with the actual certificate name is mishandled: when the subjecAltName extension is present, the expected name is compared to an...

SUSE CVE-2020-36478

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...

SUSE CVE-2021-24119

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...

In Mbed TLS before 3.1.0, psaaeadgeneratenonce allows policy bypass or oracle-based decryption when the output buffer is at memory locations accessible to an untrusted application...

SUSE CVE-2022-35409

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...

SUSE CVE-2022-46392

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...

SUSE CVE-2022-46393

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 MBEDTLSSSLDTLSCONNECTIONID is enabled and MBEDTLSSSLCIDINLENMAX 2 MBEDTLSSSLCIDOUTLENMAX...

Vulnerability of the mbedtls_mpi_exp_mod() function in Mbed TLS software, which allows a perpetrator to disclose protected information

The vulnerability of the mbedtlsmpiexpmod function in the Mbed TLS software is related to the use of cryptographic algorithms that contain vulnerabilities. Exploiting this vulnerability could allow an attacker to disclose the protected information...

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.
