UBUNTU-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...
UBUNTU-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...

CVE-2020-36478: 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. 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...
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...
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 capabilities for mbed products. A security vulnerability exists in ARM mbed TLS prior to version 2.24.0, which stems from an error in the validation handling of X.509 certificates when matching the expected...

ARM mbed TLS 安全漏洞
ARM mbed TLS is a product from ARM UK that provides secure communication and encryption for mbed products. ARM mbed TLS suffers from a denial of service vulnerability that stems from an unrestricted calculation performed by mbedtlsmpiexpmod. An attacker could exploit this vulnerability to provide...

CVE-2020-36475: Incorrect Calculation of Buffer Size
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...

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...
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...
