Debian ca-certificates: emSign ECC Root CA G3 and Comodo AAA Services root removed (DSA-6572-1)

Debian found that several eMudhra intermediate CA certificates have been compromised. Security advisory DSA-6572-1 (published 2026-10-20) provides updated ca-certificates packages that remove the "emSign ECC Root CA - G3" and "Comodo AAA Services root" root certificates. Once the update is installed, certificates chaining to these roots are no longer trusted.
