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: Use of a Broken or Risky Cryptographic Algorithm in Resilient App Host (CVE-2020-4637)

Summary Resilient App Host Beta was using weaker than expected Cryptographic Algorithm. Vulnerability Details CVEID: CVE-2020-4637 DESCRIPTION: IBM Resilient uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.

python-rsa: decryption of ciphertext leads to DoS

A flaw was found in the python-rsa package, where it does not explicitly check the ciphertext length against the key size and ignores the leading 0 bytes during the decryption of the ciphertext. This flaw allows an attacker to perform a ciphertext attack, leading to a denial of service. The highe...

CVE-2020-12619

MailMate before 1.11 automatically imported S/MIME certificates and thereby silently replaced existing ones. This allowed a man-in-the-middle attacker to obtain an email-validated S/MIME certificate from a trusted CA and replace the public key of the entity to be impersonated. This enabled the...
