Ubuntu 22.04 LTS : Node.js vulnerabilities (USN-6564-1)

The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6564-1 advisory. Hubert Kario discovered that Node.js incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted...

php: potential exposure to Marvin attack via unsafe implementation of RSA decryption API

The RSA decryption implementation using PKCS1 v1.5 padding in OpenSSL is vulnerable to a timing side-channel attack known as the Marvin Attack. This vulnerability arises because the execution time of the opensslprivatedecrypt function in PHP with OpenSSL varies based on whether a valid message is...

Siemens SIMATIC and SCALANCE Products Encryption Strength (CVE-2023-0286)

There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1STRING but the public structure definition for GENERALNAME incorrectly specified the type of the x400Address field as ASN1TYPE. This field is subsequentl...

Siemens SIMATIC and SCALANCE Products Encryption Strength (CVE-2022-4304)

A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages fo...

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...

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...
