curl security process
|
|
=====================
|
|
|
|
This document describes how security vulnerabilities should be handled in the
|
|
curl project.
|
|
|
|
Publishing Information
|
|
----------------------
|
|
|
|
All known and public curl or libcurl related vulnerabilities are listed on
|
|
[the curl website security page](https://curl.se/docs/security.html).
|
|
|
|
Security vulnerabilities **should not** be entered in the project's public bug
|
|
tracker.
|
|
|
|
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 any of the project's public
|
|
mailing lists. 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 on
|
|
[https://hackerone.com/curl](https://hackerone.com/curl). Issues filed there
|
|
reach a handful of selected and trusted people.
|
|
|
|
- Messages that do not relate to the reporting or managing of an undisclosed
|
|
security vulnerability in curl or libcurl are ignored and no further action
|
|
is required.
|
|
|
|
- A person in the security team responds to the original report to acknowledge
|
|
that a human has seen 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 synchronized with an upcoming release that contains the fix. If the
|
|
reporter, or anyone else involved, thinks the next planned release is too
|
|
far away, then a separate earlier release 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.
|
|
Figure out the CWE (Common Weakness Enumeration) number for the flaw.
|
|
|
|
- Request a CVE number from
|
|
[HackerOne](https://docs.hackerone.com/programs/cve-requests.html)
|
|
|
|
- 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.
|
|
|
|
- The security team also decides on and delivers a monetary reward to the
|
|
reporter as per the bug-bounty policies.
|
|
|
|
- No more than 10 days before release, inform
|
|
[distros@openwall](https://oss-security.openwall.org/wiki/mailing-lists/distros)
|
|
to prepare them about the upcoming public security vulnerability
|
|
announcement - attach the advisory draft for information with CVE and
|
|
current patch. 'distros' does not accept an embargo longer than 14 days and
|
|
they do not care for Windows-specific flaws.
|
|
|
|
- No more than 48 hours before the 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 time between the push and the release is used for final tests and
|
|
reviews.
|
|
|
|
- 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
|
|
curl-announce, curl-library and curl-users mailing lists.
|
|
|
|
- The security web page on the website should get the new vulnerability
|
|
mentioned.

security (at curl dot se)
|
|
------------------------------
|
|
|
|
This is a private mailing list for discussions on and about curl security
|
|
issues.
|
|
|
|
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 is not a
|
|
formal process. We basically only require that you have a long-term presence
|
|
in the curl project and you have shown an understanding for the project and
|
|
its way of working. You must have been around for a good while and you should
|
|
have no plans of vanishing in the near future.
|
|
|
|
We do not make the list of participants public mostly because it tends to vary
|
|
somewhat over time and a list somewhere will only risk getting outdated.
|
|
|
|
Publishing Security Advisories
|
|
------------------------------
|
|
|
|
1. Write up the security advisory, using markdown syntax. Use the same
|
|
subtitles as last time to maintain consistency.
|
|
|
|
2. Name the advisory file after the allocated CVE id.
|
|
|
|
3. Add a line on the top of the array in `curl-www/docs/vuln.pm'.
|
|
|
|
4. Put the new advisory markdown file in the curl-www/docs/ directory. Add it
|
|
to the git repo.
|
|
|
|
5. Run `make` in your local web checkout and verify that things look fine.
|
|
|
|
6. On security advisory release day, push the changes on the curl-www
|
|
repository's remote master branch.
|

|
Hackerone
|
|
---------
|
|
|
|
Request the issue to be disclosed. If there are sensitive details present in
|
|
the report and discussion, those should be redacted from the disclosure. The
|
|
default policy is to disclose as much as possible as soon as the vulnerability
|
|
has been published.
|
|
|
|
Bug Bounty
|
|
----------
|
|
|
|
See [BUG-BOUNTY](https://curl.se/docs/bugbounty.html) for details on the
|
|
bug bounty program.
