ID:       RUSTSEC-2020-0041
Crate:    sized-chunks
Version:  0.5.3
Date:     2020-09-06
URL:      https://rustsec.org/advisories/RUSTSEC-2020-0041
Title:    Multiple soundness issues in Chunk and InlineArray
Solution:  No safe upgrade is available!
Dependency tree:
sized-chunks 0.5.3
└── im 14.3.0
    └── sentry-core 0.19.1
        ├── sentry-panic 0.19.1

Not sure if updating im to 15.0.0 will fix it (or isn't a huge hassle).
