SCA: security update for wolfcrypt (GHSA-q95h-vc86-hv77)

medium Tenable Cloud Security Plugin ID 432920

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2019-13628)
