Code injection

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...

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 mbedtlsmpiexpmod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs...

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...

CVE-2020-36477

CVE-2020-36477 affects Mbed TLS up to version 2.24.0. The issue: when verifying X.509 certificates, the expected name is incorrectly compared to any name in the subjectAltName extension, regardless of type. This enables an attacker to impersonate a 4-byte or 16-byte domain by obtaining a certific...

CVE-2020-36476

CVE-2020-36476 affects Mbed TLS before 2.24.0 (and before 2.16.8 LTS and before 2.7.17 LTS). The issue is a missing zeroization of plaintext buffers in the TLS code path (mbedtls_ssl_read), which leaves unused application data in memory. Exploitation would rely on memory exposure and could enable...

CVE-2020-36478

CVE-2020-36478 affects Mbed TLS up to versions preceding 2.25.0 (and the LTS lines 2.16.9 and 2.7.18). The issue: a NULL algorithm parameters entry can look identical to an empty REAL array, causing a certificate to be treated as valid even when parameters do not match. If parameters do not match...

ARM mbed TLS 信任管理问题漏洞

ARM mbed TLS is a product from ARM UK that provides secure communication and encryption for mbed products. ARM mbed TLS has a security vulnerability that stems from the fact that the null algorithm parameter term is the same as the real array of size 0 and therefore the certificate is considered...
