Rust vulnerability analysis and mitigation
Overview
A critical severity vulnerability was identified in the CKB (Nervos Network) package affecting versions prior to 0.40.0. The vulnerability was discovered and published on July 26, 2021, and was assigned the identifier GHSA-45p7-c959-rgcm and CVE-2021-45700. The issue affects the CKB Rust package and its handling of DepGroup cells (GitHub Advisory, RustSec Advisory).
Technical details

Impact
When exploited, this vulnerability allows creation of malicious transactions that use dead cells as DepGroup in DepCells, resulting in crashes of all receiving nodes in the network (GitHub Advisory, RustSec Advisory).
Mitigation and workarounds
The vulnerability has been patched in version 0.40.0 of the CKB package. Users are advised to upgrade to this version or later to mitigate the risk (GitHub Advisory, RustSec Advisory).
