RUSTSEC-2020-0103 (CVE-2020-36210)

Vulnerability from osv_rustsec – Published: 2020-12-31 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

`impl Random` on arrays can lead to dropping uninitialized memory

Details

Affected versions of this crate had a panic safety issue to drop partially uninitialized array of T upon panic in a user provided function T::random(). Dropping uninitialized T can potentially cause memory corruption or undefined behavior.

The flaw was corrected in commit 565d508 by using MaybeUninit<T> to avoid possible dropping of uninitialized memory upon panic.

Severity

7.8 (High)
