wolfCrypt leaks cryptographic information via timing side channel

發布日:2022/5/24修改日:2026/4/28
也稱為:DEBIAN-CVE-2019-13628

描述

wolfSSL and wolfCrypt 4.0.0 and earlier (when configured without --enable-fpecc, --enable-sp, or --enable-sp-math) contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about the nonces used and potentially mount a lattice attack to recover the private key used. The issue occurs because ecc.c scalar multiplication might leak the bit length.
