Title:
  sbsigntool broken by update to openssl 1.0.2c

Status in openssl package in Ubuntu:
  Invalid
Status in sbsigntool package in Ubuntu:
  In Progress
Status in openssl source package in Wily:
  Invalid
Status in sbsigntool source package in Wily:
  In Progress

Bug description:
  An upload of shim-signed with no source changes is now failing to
  build in wily, because sbverify fails:

    sbverify --cert MicCorUEFCA2011_2011-06-27.crt shim.efi.signed
    warning: data remaining[1170360 vs 1289424]: gaps between PE/COFF sections?
    PKCS7 verification failed
    139919811188368:error:21075075:PKCS7 routines:PKCS7_verify:certificate verify error:pk7_smime.c:328:Verify error:unable to get issuer certificate
    Signature verification failed

  (https://launchpad.net/ubuntu/+source/shim-signed/1.10/+build/7652431)

  The package builds successfully on vivid but fails on wily.
  sbsigntool has not changed since vivid.  Upgrading to the wily version
  of libssl1.0.0 in a vivid chroot reproduces the failure.

  I'm not sure if this is a regression in libssl1.0.0 or a bug in
  sbsigntool.
