Internet Bug Bounty: OpenSSL vulnerable to the Marvin Attack (CVE-2022-4304)

A timing side channel vulnerability in OpenSSL RSA decryption was discovered that could allow plaintext recovery. By measuring decryption time, an attacker could recover RSA plaintext from captured ciphertexts after a large number of decryption attempts. All RSA padding modes were affected. The...

Node.js: Node.js is vulnerable to the Marvin Attack (timing variant of the Bleichenbacher attack against PKCS#1 v1.5 padding)

A timing side-channel vulnerability in the crypto library's privateDecrypt API allowed attackers to remotely exploit and decrypt or forge signatures when processing encrypted messages...

Side Channel Attack

libgnutls.so is vulnerable to a Side Channel Attack. The vulnerability exists due to inconsistent constant response times of ciphertexts with correct vs incorrect PKCS1 paddings, which allows an attacker to infer sensitive information...

Design/Logic Flaw

Experts Uncover Passive Method to Extract Private RSA Keys from SSH Connections

A new study has demonstrated that it's possible for passive network attackers to obtain private RSA host keys from a vulnerable SSH server by observing when naturally occurring computational faults that occur while the connection is being established. The Secure Shell SSH protocol is a method for...
