AZL-37380 CVE-2023-45287 affecting package golang for versions less than 1.21.6-1

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...

CVE-2023-45287

Summary of CVE-2023-45287 (Go): Before Go 1.20, RSA-based TLS key exchanges used math/big (not constant time). RSA blinding was applied but may not fully prevent timing leaks after removal of PKCS#1 padding, potentially enabling recovery of session key bits. Go 1.20+ switched crypto/tls to a full...

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...
