CVE-2023-4421

CVE-2023-4421 concerns the NSS library’s handling of PKCS#1 v1.5 padding, where timing side-channel leakage exposed information about padding validity and message length. This could enable Bleichenbacher-like attacks, allowing an attacker to decrypt previously intercepted PKCS#1 v1.5 ciphertext (...

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...

Marvin Attack: potential key recovery through timing sidechannels

Impact Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use that information to recover the key. Patches No patch is yet available, however work is underway to migrate...

GHSA-4GRX-2X9W-596C Marvin Attack: potential key recovery through timing sidechannels

The Marvin Attack is a timing sidechannel vulnerability which allows performing RSA decryption and signing operations as an attacker with the ability to observe only the time of the decryption operation performed withthe private key. A recent survey of RSA implementations found that the Rust rsa...

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...
