In the Bouncy Castle JCE Provider versions 1.51 to 1.55, a carry propagation bug was introduced in the implementation of squaring for several raw math classes have been fixed (org.bouncycastle.math.raw.Nat???). These classes are used by our custom elliptic curve implementations (org.bouncycastle.math.ec.custom.**), so there was the possibility of rare (in general usage) spurious calculations for elliptic curve scalar multiplications. Such errors would have been detected with high probability by the output validation for our scalar multipliers. Upstream patch: https://github.com/bcgit/bc-java/commit/790642084c4e0cadd47352054f868cc8397e2c00#diff-e5934feac8203ca0104ab291a3560a31
Created bouncycastle tracking bugs for this issue: Affects: epel-all [bug 1588689] Affects: fedora-all [bug 1588691]
(In reply to Pedro Sampaio from comment #1) > Affects: fedora-all [bug 1588691] Fedora already carries bouncycastle newer than 1.56, so I will close this bug.
