CVE-2020-36425

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-2020-36426

An explicit technical detail: CVE-2020-36426 affects Arm Mbed TLS prior to 2.24.0, where mbedtls_x509_crl_parse_der has a one-byte buffer over-read. The connected documents corroborate this in multiple advisories (e.g., GLSA-202301-08 and Debian DLA/Debian advisories) and note a fixed release in ...

CVE-2020-36421

CVE-2020-36421 affects Arm Mbed TLS up to version 2.22.x (before 2.23.0). A side-channel in modular exponentiation could disclose an RSA private key used in a secure enclave, causing partial confidentiality loss of the key material. The vulnerability is documented across multiple sources (e.g., A...

CVE-2020-36425

Arm Mbed TLS before 2.24.0 contains a revocation check flaw for CRLs: it inconsistently honors revocation via CRL by using a revocationDate check, which can be exploited by altering the local clock. This can affect certificate revocation handling. Remediation is to upgrade to version 2.24.0 or la...
