Affected: time-rs time

In Rust time crate from version 0.2.7 and before version 0.2.23, unix-like operating systems may segfault due to dereferencing a dangling pointer in specific circumstances. This requires the user to set any environment variable in a different thread than the affected functions. The affected functions are time::UtcOffset::local_offset_at, time::UtcOffset::try_local_offset_at, time::UtcOffset::current_local_offset, time::UtcOffset::try_current_local_offset, time::OffsetDateTime::now_local and time::OffsetDateTime::try_now_local. Non-Unix targets are unaffected. This includes Windows and wasm. The issue was introduced in version 0.2.7 and fixed in version 0.2.23.

 https://cve.radiocsirt.org/vuln/rustsec-2020-0071 RUSTSEC-2020-0071 — Potential segfault in the time crate 2026-10-05T00:19:03.408004+00:00

Affected: crates.io: time

### Impact

The affected functions set environment variables without synchronization. On Unix-like operating systems, this can crash in multithreaded programs. Programs may segfault due to dereferencing a dangling pointer if an environment variable is read in a different thread than the affected functions. This may occur without the user's knowledge, notably in the Rust standard library or third-party libraries.

The affected functions from time 0.2.7 through 0.2.22 are:

- `time::UtcOffset::local_offset_at` - `time::UtcOffset::try_local_offset_at` - `time::UtcOffset::current_local_offset` - `time::UtcOffset::try_current_local_offset` - `time::OffsetDateTime::now_local` - `time::OffsetDateTime::try_now_local`

The affected functions in time 0.1 (all versions) are:

- `time::at_utc` - `time::at` - `time::now` - `time::tzset`

Non-Unix targets (including Windows and wasm) are unaffected.

### Patches

Pending a proper fix, the internal method that determines the local offset has been modified to always return `None` on the affected operating systems. This has the effect of returning an `Err` on the `try_*` methods and `UTC` on the non-`try_*` methods.

Users and library authors with time in their dependency tree should perform `cargo update`, which will pull in the updated, unaffected code.

Users of time 0.1 do not have a patch and should upgrade to an unaffected version: time 0.2.23 or greater or the 0.3 series.
