Name of the Vulnerable Software and Affected Versions: Trusted Firmware Mbed TLS versions prior to 2.23.0 Description: A timing side channel in the mbedtls ssl decrypt buf function in the library/ssl msg.c file allows an attacker to recover secret key information. This issue affects CBC mode due ...

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...

Mbed TLS -- Local side channel attack on classical CBC decryption in (D)TLS

Manuel Pégourié-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...

CVE-2020-8911

A flaw was found in the AWS S3 Crypto SDK that allows users to encrypt files stored in S3 buckets with AES-CBC, without computing a MAC on the data. This allows for a padding oracle, enabling attackers with both write access to the target S3 bucket and the ability to observe the result of valid...

CVE-2020-8911

A padding oracle vulnerability exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. The SDK allows users to encrypt files with AES-CBC without computing a Message Authentication Code MAC, which then allows an attacker who has write access to the target's S3 bucket and can observe...

CVE-2020-8911

CVE-2020-8911 describes a padding oracle in the AWS S3 Crypto SDK for Go (older GoLang S3 encryption client). The vulnerability arises because AES-CBC encryption was used without a MAC, enabling an attacker with write access to the target S3 bucket to observe decryption outcomes and reconstruct p...

MGASA-2020-0308 Updated botan2 packages fix security vulnerability

The CBC padding operations were not constant time and as a result would leak the length of the plaintext values which were being padded to an attacker running a side channel attack via shared resources such as cache or branch predictor. No information about the contents was leaked, but the length...
