Hi,
The following vulnerability was published for wolfssl.
CVE-2022-42961[0]:
| 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.)
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
