Fedora 34: FEDORA-2021-d0ba1901ca Critical: Rust Memory Issues

Rust is a systems programming language that runs blazingly fast, prevents

segfaults, and guarantees thread safety.

This package includes the Rust compiler and documentation generator.

Security fixes for CVE-2020-36323, CVE-2021-28876, CVE-2021-28878,

CVE-2021-28879, and CVE-2021-31162. These are memory safety bugs in the Rust

standard library. Because it is statically linked, affected applications will

need to be rebuilt to benefit from the fixes. The actual security implications

will depend on how these APIs are used in each particular case.
