RUSTSEC-2020-0071: time: Potential segfault in the time crate



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:

Non-Unix targets are unaffected. This includes Windows and wasm.


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 a the updated, unaffected code.


No workarounds are known.
