CVE-2021-29936
Rust vulnerability analysis and mitigation

Overview

An issue was discovered in the adtensor crate through 2021-01-11 for Rust. The vulnerability involves a drop of uninitialized memory via the FromIterator implementation for Vector and Matrix (RustSec Advisory).

Technical details

The vulnerability stems from the FromIterator methods for Vector and Matrix types. These methods rely on the type parameter N to allocate space in the iterable. When the N type parameter is larger than the number of items returned by the iterator, it can result in uninitialized memory being left in the Vector or Matrix type which subsequently gets dropped. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 CRITICAL with vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (RustSec Advisory).

Impact

The vulnerability can lead to memory corruption issues, potentially exposing sensitive information or enabling arbitrary code execution. The CVSS score of 9.8 indicates critical severity with potential for high impact on confidentiality, integrity, and availability of affected systems (RustSec Advisory).

Mitigation and workarounds

As of the advisory date, there are no patched versions available for this vulnerability. Users of the adtensor crate should consider alternative implementations or carefully review their use of FromIterator implementations for Vector and Matrix types (RustSec Advisory).
