CVE-2019-11090

Cryptographic timing vulnerabilities were discovered in certain versions of the Trusted Platform Module (TPM) firmware distributed by Intel and STMicroelectronics. Software that uses the TPM to compute ECDSA signatures could leak information through the timing of ECDSA signature operations, allowing an attacker to recover parts of the private key.

Mitigation

To remediate this vulnerability, install relevant firmware updates from your hardware vendor and follow their advice to regenerate keys that may be vulnerable or compromised.
