"The remote OracleVM system is missing necessary patches to address
critical security updates :

  - Added nss-vendor.patch to change vendor

  - Temporarily disable some tests until expired
    PayPalEE.cert is renewed

  - Backport upstream fix for (CVE-2018-12384)

  - Remove nss-lockcert-api-change.patch, which turned out
    to be a mistake (the symbol was not exported from
    libnss)

  - Restore CERT_LockCertTrust and CERT_UnlockCertTrust back
    in cert.h

  - rebuild

  - Keep legacy code signing trust flags for backwards
    compatibility

  - Decrease the iteration count of PKCS#12 for
    compatibility with Windows

  - Fix deadlock when a token is re-inserted while a client
    process is running

  - Ignore tests which only works with newer nss-softokn

  - Use the correct tarball of NSS 3.36 release

  - Ignore EncryptDeriveTest which only works with newer
    nss-softokn

  - Don't skip non-FIPS and ECC test cases in ssl.sh

  - Rebase to NSS 3.36.0

  - Rebase to NSS 3.36.0 BETA

  - Remove upstreamed nss-is-token-present-race.patch

  - Revert the upstream changes that default to sql database

  - Replace race.patch and nss-3.16-token-init-race.patch
    with a proper upstream fix

  - Don't restrict nss_cycles to sharedb

  - Rebase to NSS 3.34.0"
