Description

Potential segfault in localtime_r invocations

Details
Package chrono
Version 0.4.19
URL https://github.com/chronotope/chrono/issues/499
Date 2020-11-10
Impact

Unix-like operating systems may segfault due to dereferencing a dangling pointer in specific circumstances. This requires an environment variable to be set in a different thread than the affected functions. This may occur without the user's knowledge, notably in a third-party library.

Workarounds

No workarounds are known.

Research direction

Start with the RUSTSEC-2020-0159 advisory and its linked chrono issue, focusing on the affected chrono 0.4.19 dependency and the localtime_r conditions described there. Inspect this repository’s Rust dependency declarations to determine whether chrono is used and how it can be updated; done means the vulnerable dependency is no longer present and relevant checks pass.
