wolfssl: An issue was discovered in wolfSSL before 5.5.0
CVE-2022-42961 is fixed in wolfssl on 1 platform, first by DEBIAN-CVE-2022-42961, released October 15, 2022. It is not reported as exploited. Patch Radar priority: Routine.
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.)
