CVE-2023-6935

wolfSSL SP Math All RSA implementation is vulnerable to the Marvin Attack, new variation of a timing Bleichenbacher style attack, when built with the following options to configure: --enable-all CFLAGS="-DWOLFSSLSTATICRSA" The define “WOLFSSLSTATICRSA” enables static RSA cipher suites, which is n...

CVE-2023-6935

The CVE-2023-6935 entry concerns wolfSSL SP Math All RSA when built with static RSA (WOLFSSL_STATIC_RSA). The Marvin Attack, a timing Bleichenbacher-style attack variant, can decrypt ciphertexts and forge signatures after many observations. However, the default builds since wolfSSL 3.6.6 disable ...
