FreeBSD : messagelib -- HTML email can open browser window automatically (c7b1af20-f34f-11e8-9cde-e0d55e2a8bf9)

High Nessus Plugin ID 119273


The remote FreeBSD host is missing a security-related update.


Albert Astals Cid reports :

messagelib is the library used by KMail to display emails.

messagelib by default displays emails as plain text, but gives the user an option to 'Prefer HTML to plain text' in the settings and if that option is not enabled there is way to enable HTML display when an email contains HTML.

Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML.

This happens even if the option to allow the HTML emails to access remote servers is disabled in KMail settings.

This means that the owners of the servers referred in the email can see in their access logs your IP address.


Update the affected package.
