Return of Coopersmith's Attack / ROCA (CVE-2017-15361)

In 2017 a team of researchers from the Centre for Research on Cryptography and Security (CRoCS) at Masaryk University discovered a vulnerability in the RSA key generation function of hardware chips produced by the company Infineon.

This affected a wide variety of products. Most notably the government of Estonia had to replace a large number of eID cards.
