Vulnerability from github – Published: 2021-08-25 20:57 – Updated: 2021-08-24 18:54

Summary

Memory corruption in array-tools

Details

An issue was discovered in the array-tools crate before 0.3.2 for Rust. Affected versions of this crate don't guard against panics, so that partially uninitialized buffer is dropped when user-provided T::clone() panics in FixedCapacityDequeLike<T, A>::clone(). This causes memory corruption.

Severity

9.8 (Critical)

RUSTSEC-2020-0132 (CVE-2020-36452)

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

Summary

`FixedCapacityDequeLike::clone()` can cause dropping uninitialized memory

Details

Affected versions of this crate don't guard against panics, so that partially uninitialized buffer is dropped when user-provided T::clone() panics in FixedCapacityDequeLike<T, A>::clone(). This causes memory corruption.

Severity

9.8 (Critical)
