CVE-2020-35891: 
Rust vulnerability analysis and mitigation

An issue was discovered in the ordnung crate through 2020-09-03 for Rust. The compact::Vec implementation violates memory safety through a remove() double free vulnerability (NVD, RustSec).

The vulnerability exists in the compact::Vec implementation where the remove() function is not panic-safe and causes a double-free condition when an index larger than the length is provided. The issue has been assigned a CVSS v3.1 Base Score of 7.5 (HIGH) with vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (RustSec).

The vulnerability can lead to memory corruption through double-free conditions, which could result in program crashes and potential denial of service (RustSec).

The vulnerability can be triggered when calling the remove() function with an index larger than the vector's length. No user interaction is required, and the attack complexity is considered low (RustSec).

As of the last available information, there are no patched versions available for this vulnerability. Users of the ordnung crate should consider using alternative implementations or ensure proper bounds checking before calling remove() (RustSec).
