CVE-2022-42961 Information

Description

An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys such as in server-side TLS connections might leak faulty ECC signatures. These signatures can be processed via an advanced technique for ECDSA key recovery. (In 5.5.0 and later WOLFSSL_CHECK_SIG_FAULTS can be used to address the vulnerability.)
