  Changed paths:
    M crypto/bn/bn_recp.c

  Log Message:
  -----------
  Check for 0 modulus in BN_RECP_CTX_set.
The function BN_RECP_CTX_set did not check whether arg d is zero,
in which case an early failure should be returned to the invoker.
This is a similar fix to the cognate defect of CVE-2015-1794.

Fixes #21111
