Security fixes will be backported only to the webpki versions for which the original semver-compatible release was published less than 2 years ago.

For example, as of 2023-06-13 the latest release is 0.100.1

• 0.100.0 was released in March of 2023
• 0.17.0 was released in August of 2017

Therefore 0.100.x will be updated, while 0.17.x will not be.

Please report security bugs by email to rustls-security@googlegroups.com. We'll then:

• Prepare a fix and regression tests.
• Backport the fix and make a patch release for most recent release.
• Submit an advisory to rustsec/advisory-db.
• Refer to the advisory on the main README.md and release notes.
