The visible post says interest is limited and leaves open whether other mail apps inherit the NSS trust store.

An oss-security reply from Steffen Nurpmeso quotes Hanno Böck on the Comodo AAA Services root and S/MIME. Böck says further investigation is unlikely and asks whether other mail applications use the NSS or Thunderbird certificate store as an S/MIME trust anchor. The snippet also asks whether those applications properly check X.509 paths, then cuts off.

Unconfirmed: The feed snippet is incomplete, and no finding about other mail clients is confirmed.

Key facts
  • The questions concern clients that source the NSS or Thunderbird certificate store.
  • Path validation is raised but not answered in the visible text.
  • No affected product versions or fixes are stated.
