This update fixes a critical security issue. An attacker was able to read protected information or even execute their own
program code without authentication.
Improved macro detection in email attachments
Now macros will also be recognized if office documents have been mailed directly (not as attachment) or if they are attached
to an attached email.
New categories for the commercial URL filter
New categories have been added to the commercial URL filter: Arms and weapons, DNS-over-HTTPS, Movies and series with questionable
legal status, Education, Restaurants and recipe sites, Buy or rent a place to live, Stock markets and trading systems.
Adding new certificates to the keyring
For each certificate the corresponding root and intermediate CA certificates have to be stored. Previously the CA certificates
had to be uploaded manually for each new certificate. Now the certificates of well-known root CAs will be added automatically.
Certificates of intermediate CAs will be cached upon the first upload and added automatically when required by subsequent
certificates. Adding multiple similar certificates as required by the S/MIME gateway feature becomes much more convenient
in this way.
