Today, the Debian Team has announced the first update of the latest stable distribution Debian 7 Wheezy. In this update we can find some security corrections and few more adjustments for other big problems. Security advisories were already published separately and are referenced where available.
This update does not constitute a new version of Debian 7 and only updates some of the packages included. You don;t need to throw away your 7 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.
Those who frequently install updates from security.debian.org won’t have to update many packages and most updates from security.debian.org are included in this update.
New installation media and CD and DVD images containing updated packages will be available soon at the regular locations.
Upgrading to this revision online is usually done by pointing the aptitude (or apt) package tool (see the sources.list(5) manual page) to one of Debian’s many FTP or HTTP mirrors. A comprehensive list of mirrors is available at: http://www.debian.org/mirror/list
