2.4.0 (older version) ub-risk-1

From google/supply-chain copy of google/rust-crate-audits. By Benjamin Saunders.

Reviewed in CL 610738461

2.3.1 (older version) unknown

From kornelski/crev-proofs copy of git.savannah.gnu.org.

Packaged for Guix (crates-io)

1.8.2 (older version) safe-to-deploy

From mozilla/supply-chain copy of hg. By John Schanck.

This crate contains unsafe code for bitwise casts to/from binary16 floating-point format. I've reviewed these and found no issues. There are no uses of ambient capabilities.

1.8.2 (older version) unknown

From kornelski/crev-proofs copy of salsa.debian.org.

Only in debcargo (unstable). Changelog:

• Team upload.
• Package half 1.8.2 from crates.io using debcargo 2.6.1
• Disable zerocopy feature, it's not compatible with the new version of zerocopy.
• Skip a failling floating point test on armel, floating point with very small values on armel is known to be buggy.

cargo-vet does not verify reviewers' identity. You have to fully trust the source the audits are from.

ub-risk-3 (implies ub-risk-4)

Mild unsoundness or suboptimal soundness.

Full description of the audit criteria can be found at https://github.com/google/rust-crate-audits/blob/main/auditing_standards.md#ub-risk-3

ub-risk-4

Implied by other criteria

Extreme unsoundness.

Full description of the audit criteria can be found at https://github.com/google/rust-crate-audits/blob/main/auditing_standards.md#ub-risk-4

does-not-implement-crypto (implies crypto-safe)

Inspection reveals that the crate in question does not attempt to implement any cryptographic algorithms on its own.

Note that certification of this does not require an expert on all forms of cryptography: it's expected for crates we import to be "good enough" citizens, so they'll at least be forthcoming if they try to implement something cryptographic. When in doubt, please ask an expert.

crypto-safe

Implied by other criteria

All crypto algorithms in this crate have been reviewed by a relevant expert.

Note: If a crate does not implement crypto, use does-not-implement-crypto, which implies crypto-safe, but does not require expert review in order to audit for.

ub-risk-1 (implies ub-risk-2)

Excellent soundness.

Full description of the audit criteria can be found at https://github.com/google/rust-crate-audits/blob/main/auditing_standards.md#ub-risk-1

ub-risk-2 (implies ub-risk-3)

Implied by other criteria

Negligible unsoundness or average soundness.

Full description of the audit criteria can be found at https://github.com/google/rust-crate-audits/blob/main/auditing_standards.md#ub-risk-2

safe-to-deploy (implies safe-to-run)

This crate will not introduce a serious security vulnerability to production software exposed to untrusted input. More…

1.8.2 (older version) Rating: Positive Thoroughness: Medium Understanding: Medium

by ThomasdenH on 2022-01-11

A small crate to find the rust compiler version as well as some metadata. Contains plenty of tests and handles versioning quirks

1.3.0 (older version) Rating: Positive Thoroughness: Low Understanding: Low
