UBUNTU-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...

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...
Security Bulletin: OpenSSL (Publicly disclosed vulnerability) for IBM b-type switches and directors
Summary Fixes are released for OpenSSL Publicly disclosed vulnerability for IBM b-type switches and directors. Vulnerability Details CVEID: CVE-2019-1547 DESCRIPTION: OpenSSL could allow a local authenticated attacker to obtain sensitive information, caused by the ability to construct an EC group...
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...
CVE-2020-8911 CBC padding oracle in AWS S3 Crypto SDK for GoLang
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: Use of a Broken or Risky Cryptographic Algorithm

UBUNTU-CVE-2020-12401
During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox 80 and Firefox for Android 80...

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...
