EUVD-2026-31396

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

Factoring 2048-bit Numbers Using 20 Million Qubits

This theoretical paper shows how to factor 2048-bit RSA moduli with a 20-million qubit quantum computer in eight hours. It's interesting work, but I don't want overstate the risk. We know from Shor's Algorithm that both factoring and discrete logs are easy to solve on a large, working quantum...

ROC - Infineon RSA Vulnerability

This tool is related to ACM CCS 2017 conference paper 124 Return of the Coppersmith’s Attack: Practical Factorization of Widely Used RSA Moduli. It enables you to test public RSA keys for a presence of the described vulnerability. Update : The paper of the attack is already online, ACM version...
