CURL SECURITY FOR DEVELOPERS
|
|
|
|
This document is intended to provide guidance to curl developers on how
|
|
security vulnerabilities should be handled.
|
|
|
|
PUBLISHING INFORMATION
|
|
|
|
All known and public curl or libcurl related vulnerabilities are listed at
|
|
http://curl.haxx.se/docs/security.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 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
|
|
privately to curl-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 curl or libcurl 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.org[1] 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
|
|
curl-announce, curl-library and curl-users mailing lists.
|
|
|
|
- The security web page on the web site should get the new vulnerability
|
|
mentioned.
