c-ares security |
|
=============== |
|
|
|
This document is intended to provide guidance on how security vulnerabilities |
|
should be handled in the c-ares project. |
|
|
|
Publishing Information |
|
---------------------- |
|
|
|
All known and public c-ares vulnerabilities will be listed on [the c-ares web |
|
site](https://c-ares.haxx.se/vulns.html). |
|
|
|
Security vulnerabilities should not be entered in the project's public bug |
|
tracker unless the necessary configuration is in place to limit access to the |
|
issue to only the reporter and the project's security team. |
|
|
|
Vulnerability Handling |
|
---------------------- |
|
|
|
The typical process for handling a new security vulnerability is as follows. |
|
|
|
No information should be made public about a vulnerability until it is |
|
formally announced at the end of this process. That means, for example that a |
|
bug tracker entry must NOT be created to track the issue since that will make |
|
the issue public and it should not be discussed on the project's public |
|
mailing list. Also messages associated with any commits should not make any |
|
reference to the security nature of the commit if done prior to the public |
|
announcement. |
|
|
|
- The person discovering the issue, the reporter, reports the vulnerability |
|
privately to `c-ares-security@haxx.se`. That's an email alias that reaches a |
|
handful of selected and trusted people. |
|
|
|
- Messages that do not relate to the reporting or managing of an undisclosed |
|
security vulnerability in c-ares are ignored and no further action is |
|
required. |
|
|
|
- A person in the security team sends an e-mail to the original reporter to |
|
acknowledge the report. |
|
|
|
- The security team investigates the report and either rejects it or accepts |
|
it. |
|
|
|
- If the report is rejected, the team writes to the reporter to explain why. |
|
|
|
- If the report is accepted, the team writes to the reporter to let him/her |
|
know it is accepted and that they are working on a fix. |
|
|
|
- The security team discusses the problem, works out a fix, considers the |
|
impact of the problem and suggests a release schedule. This discussion |
|
should involve the reporter as much as possible. |
|
|
|
- The release of the information should be "as soon as possible" and is most |
|
often synced with an upcoming release that contains the fix. If the |
|
reporter, or anyone else, thinks the next planned release is too far away |
|
then a separate earlier release for security reasons should be considered. |
|
|
|
- Write a security advisory draft about the problem that explains what the |
|
problem is, its impact, which versions it affects, solutions or |
|
workarounds, when the release is out and make sure to credit all |
|
contributors properly. |
|
|
|
- Request a CVE number from |
|
[distros@openwall](http://oss-security.openwall.org/wiki/mailing-lists/distros) |
|
when also informing and preparing them for the upcoming public security |
|
vulnerability announcement - attach the advisory draft for information. Note |
|
that 'distros' won't accept an embargo longer than 19 days. |
|
|
|
- Update the "security advisory" with the CVE number. |
|
|
|
- The security team commits the fix in a private branch. The commit message |
|
should ideally contain the CVE number. This fix is usually also distributed |
|
to the 'distros' mailing list to allow them to use the fix prior to the |
|
public announcement. |
|
|
|
- At the day of the next release, the private branch is merged into the master |
|
branch and pushed. Once pushed, the information is accessible to the public |
|
and the actual release should follow suit immediately afterwards. |
|
|
|
- The project team creates a release that includes the fix. |
|
|
|
- The project team announces the release and the vulnerability to the world in |
|
the same manner we always announce releases. It gets sent to the c-ares |
|
mailing list and the oss-security mailing list. |
|
|
|
- The security web page on the web site should get the new vulnerability |
|
mentioned. |

C-ARES-SECURITY (at haxx dot se) |

-------------------------------- |
|
|
|
Who is on this list? There are a couple of criteria you must meet, and then we |
|
might ask you to join the list or you can ask to join it. It really isn't very |
|
formal. We basically only require that you have a long-term presence in the |
|
c-ares project and you have shown an understanding for the project and its way |
|
of working. You must've been around for a good while and you should have no |
|
plans in vanishing in the near future. |
|
|
|
We do not make the list of partipants public mostly because it tends to vary |
|
somewhat over time and a list somewhere will only risk getting outdated.
