Vulnerability from github – Published: 2022-06-17 00:16 – Updated: 2022-06-17 00:16

Summary

Optional `Deserialize` implementations lacking validation

Details

When activating the non-default feature serialize, most structs implement serde::Deserialize without sufficient validation. This allows breaking invariants in safe code, leading to:

Undefined behavior in as_string() methods (which use std::str::from_utf8_unchecked() internally).
Panics due to failed assertions.

See https://github.com/gz/rust-cpuid/issues/43.
