Debian takes security very seriously. We handle all security problems brought to our attention and ensure that they are corrected within a reasonable timeframe. Many advisories are coordinated with other free software vendors and are published the same day a vulnerability is made public and we also have a Security Audit team that reviews the archive looking for new or unfixed security bugs.
Experience has shown that
security through obscurity does not work. Public
disclosure allows for more rapid and better solutions to security problems. In
that vein, this page addresses Debian's status with respect to various known
security holes, which could potentially affect Debian.
Debian also participates in security standardization efforts: the Debian Security Advisories are CVE-Compatible (review the cross references) and Debian is represented in the Board of the Open Vulnerability Assessment Language project.
In order to receive the latest Debian security advisories, subscribe to the debian-security-announce mailing list.
You can use apt to easily get the latest security updates. This requires a line such as
deb http://security.debian.org/ jessie/updates main contrib non-free
/etc/apt/sources.list file. Then execute
apt-get update && apt-get upgrade to download and apply
the pending updates.
The security archive is signed with the normal Debian archive
These web pages include a condensed archive of security advisories posted to the debian-security-announce list.

The latest Debian security advisories are also available in RDF format. We also offer a second file that includes the first paragraph of the corresponding advisory so you can see in it what the advisory is about.
The older security advisories are also available: 2016, 2015, 2014, 2013, 2012, 2011, 2010, 2009, 2008, 2007, 2006, 2005, 2004, 2003, 2002, 2001, 2000, 1999, 1998, 1997 and undated security advisories, included for posterity.
Debian distributions are not vulnerable to all security problems. The Debian Security Tracker collects all information about the vulnerability status of Debian packages, and can be searched by CVE name or by package.
