Security fixes will be backported only to the rustls versions for which the original semver-compatible release was published less than 2 years ago.
For example, as of 2024-04-18 the latest release is 0.23.4.
- 0.23.0 was released in February of 2024
- 0.22.0 was released in December of 2023
- 0.21.0 was released in March of 2023
- 0.20.0 was released in September of 2021
- 0.19.0 was released in November of 2020
Therefore 0.23.x, 0.22.x and 0.21.x will be updated, while 0.20.x and 0.19.x will not be.
Note: We use the date of crates.io
publication when evaluating the security
policy. For example, while the Rustls 0.20.0 GitHub release note was created
Jul, 2023 the actual release in crates.io
was published in Sept. 2021.
Please report security bugs via github. 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.
If you're looking for security bugs, this crate is set up for
cargo fuzz
but would benefit from more runtime, targets and corpora.
