+security advisories, and maintaining security.debian.org.
+
+
+
+
+
+When you become aware of a security-related bug in a Debian package,

+about the problem, and promptly contact the security team at
+&email-security-team;.
+Useful information includes, for example:
+
+
+Unlike most other activities within Debian, information about security
+issues must sometimes be kept private for a time. Whether this is the
+case depends on the nature of the problem and corresponding fix, and
+whether it is already a matter of public knowledge.
+
+There are a few ways a developer can learn of a security problem:
+
+
+ In all cases if the person who reports the problem asks to not
+ disclose the information that should be respected, with the obvious
+ exception of informing the security team (make sure you tell the
+ security team that the information can not be disclosed).
+
+
+Please note that if secrecy is needed you can also not upload a fix to
+unstable (or anywhere else), since the changelog and diff information
+for unstable is public.
+
+
+There are two reasons for releasing information even though secrecy is
+requested: the problem has been known for a while, or that the problem
+or exploit has become public.
+
+
+Security advisories are only issued for the current, released stable
+distribution, not for testing or unstable. When released, advisories
+are sent to the &email-debian-security-announce;
+mailing list and posted on
+One way that you can assist the security team in their duties is to
+provide fixed packages suitable for a security advisory for the stable
+Debian release.
+
+ When an update is made to the stable release, care must be taken to
+ avoid changing system behavior or introducing new bugs. In order to
+ do this, make as few changes as possible to fix the bug. Users and
+ administrators rely on the exact behavior of a release once it is
+ made, so any change that is made might break someone's system.
+ This is especially true of libraries: make sure you never change the
+ API or ABI, no matter how small the change.
+
+This means that moving to a new upstream version is not a good
+solution. Instead, the relevant changes should be back-ported to the
+version present in the current stable Debian release. Generally,
+upstream maintainers are willing to help if needed. If not, the
+Debian security team may be able to help.
+
+In some cases, it is not possible to back-port a security fix, for
+example when large amounts of source code need to be modified or
+rewritten. If this happens, it may be necessary to move to a new
+upstream version. However, you must always coordinate that with the
+security team beforehand.
+
+Related to this is another important guideline: always test your
+changes. If you have an exploit available, try it and see if it
+indeed succeeds on the unpatched package and fails on the fixed
+package. Test other, normal actions as well, as sometimes a security
+fix can break seemingly unrelated features in subtle ways.
+
+When packaging the fix, keep the following points in mind:
+
+
+DO NOT upload a package to the security upload queue without
+prior authorization from the security team. If the package does not
+exactly meet the team's requirements, it will cause many problems and
+delays in dealing with the unwanted upload.
+
+Once you have created and tested the new package and it has been
+approved by the security team, it needs to be uploaded so that it can
+be installed in the archives. For security uploads, the place to
+upload to is
+ftp://security.debian.org/pub/SecurityUploadQueue/ .
+
+
+Once an upload to the security queue has been accepted, the package
+will automatically be rebuilt for all architectures and stored for
+verification by the security team.
+
+
+Uploads which are waiting for acceptance or verification are only
+accessible by the security team. This is necessary since there might
+be fixes for security problems that cannot be disclosed yet.
+
+
+If a member of the security team accepts a package, it will be
+installed on security.debian.org as well as the proper
+distribution-proposed-updates on ftp-master or in the non-US
+archive.
