CVE-2017-15361 at MITRE

Description

The Infineon RSA library 1.02.013 in Infineon Trusted Platform Module (TPM) firmware, such as versions before 0000000000000422 - 4.34, before 000000000000062b - 6.43, and before 0000000000008521 - 133.33, mishandles RSA key generation, which makes it easier for attackers to defeat various cryptographic protection mechanisms via targeted attacks, aka ROCA. Examples of affected technologies include BitLocker with TPM 1.2, YubiKey 4 (before 4.3.5) PGP key generation, and the Cached User Data encryption feature in Chrome OS.

Note from the SUSE Security Team

To our knowledge no SUSE or openSUSE package has facilitated the TPM for RSA key generation so far, so we should not have created keys ourselves. For more information on this vulnerability, including tools to check for weak keys, please check out the ROCA report page.
