Description

An unauthorized SSL certificate has been found in the wild issued for the DigiNotar Certificate Authority, obtained through a security compromise with said company. Debian, like other software distributors, has as a precaution decided to disable the DigiNotar Root CA by default in its ca-certificates bundle.

For other software in Debian that ships a CA bundle, like the Mozilla suite, updates are forthcoming.
