[Bug 1234649] Re: UEFI shim verification against microsoft-uefica-public.pem fails with 20131003 saucy images

[Launchpad Bug Tracker]

This bug was fixed in the package sbsigntool - 0.6-0ubuntu4~12.04.2

---------------
sbsigntool (0.6-0ubuntu4~12.04.2) precise; urgency=medium

  * debian/patches/0001-Support-openssl-1.0.2b-and-above.patch: handle the
    case where we can't get the issuer certificate, which typically happens
    after 1.0.2b; but it appears that 1.0.1f includes that check too, which
    fails in sbsigntool. (LP: #1474541)
  * debian/patches/ignore-certificate-expiries.patch: ignore certificate
    expiries when verifying signatures. (LP: #1234649)

Title:
  UEFI shim verification against microsoft-uefica-public.pem fails with
  20131003 saucy images

Status in sbsigntool package in Ubuntu:
  Fix Released
Status in sbsigntool source package in Precise:
  Fix Released
Status in sbsigntool source package in Quantal:
  Won't Fix
Status in sbsigntool source package in Raring:

Bug description:
  [Impact]
  Validating signature using sbsigntool for EFI binaries on Precise.

  [Test case]
  1) pull-lp-source shim-signed
  2) sbverify --cert MicCorUEFCA2011_2011-06-27.crt shim.efi.signed

  [Regression potential]
  This is dependent on the date of the system being correct -- wrong date may cause an unexpected success or failure of the test case.
