Peter, All,

On 2020-01-18 13:44 +0100, Yann E. MORIN spake thusly:
> commit: https://git.buildroot.net/buildroot/commit/?id=a7186d0913f4df2f86439abfdadbaec60f359818
> branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
> 
> Fix CVE-2019-18222: Our bignum implementation is not constant
> time/constant trace, so side channel attacks can retrieve the blinded
> value, factor it (as it is smaller than RSA keys and not guaranteed to
> have only large prime factors), and then, by brute force, recover the
> key. Reported by Alejandro Cabrera Aldaya and Billy Brumley.

This one is a candidate as a security backport to the stable branches.

Regards,
Yann E. MORIN.
