[SECURITY] Fedora 31 Update: mbedtls-2.16.8-1.fc31

Mbed TLS is a light-weight open source cryptographic and SSL/TLS library written in C. Mbed TLS makes it easy for developers to include cryptographic and SSL/TLS capabilities in their embedded applications with as little hassle as possible. FOSS License Exception:...

FreeBSD : Mbed TLS -- Local side channel attack on classical CBC decryption in (D)TLS (4c69240f-f02c-11ea-838a-0011d823eebd)

Manuel Pegourie-Gonnard reports : When decrypting/authenticating DTLS record in a connection using a CBC ciphersuite without the Encrypt-then-Mac extension RFC 7366, Mbed TLS used dummy rounds of the compression function associated with the hash used for HMAC in order to hide the length of the...

FreeBSD : Mbed TLS -- Local side channel attack on RSA and static Diffie-Hellman (bcdeb6d2-f02d-11ea-838a-0011d823eebd)

Manuel Pegourie-Gonnard reports : An attacker with access to precise enough timing and memory access information typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world can recover the private keys used in RSA or static finite-field...

DEBIAN-CVE-2020-16150

A Lucky 13 timing side channel in mbedtlsssldecryptbuf in library/sslmsg.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...

PT-2021-6568

Name of the Vulnerable Software and Affected Versions Arm Mbed TLS versions prior to 2.24.0 Description The issue is related to a buffer over-read in the mbedtls x509 crl parse der function, which can lead to a denial of service. This can be exploited by a remote attacker. The function is part of...

CVE-2020-16150

CVE-2020-16150 describes a Lucky 13 timing side-channel in mbedtls_ssl_decrypt_buf (library/ssl_msg.c) of Trusted Firmware Mbed TLS up to version 2.23.0. The side-channel arises from padding-length dependent timing in CBC mode, enabling an attacker to recover secret key information. The vulnerabi...

Information Disclosure

Arm Mbed TLS is vulnerable to Information Disclosure. 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...

Sensitive Information Disclosure

Arm Mbed TLS is vulnerable to sensitive information leakage. When deterministic ECDSA is enabled, it uses 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...

Information Disclosure

mbedtls is vulnerable to information disclosure. The vulnerability exists as 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 v...
