How to fix?

Upgrade Debian:unstable rustc to version 1.53.0+dfsg1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rustc package and not the rustc package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

In the standard library in Rust before 1.52.0, the Zip implementation has a panic safety issue. It calls __iterator_get_unchecked() more than once for the same index when the underlying iterator panics (in certain conditions). This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
