Rust vulnerability analysis and mitigation
Overview
The vulnerability (GHSA-mcmr-49x3-4jqm) affects the TypeIdSystemScript resume functionality in CKB (Nervos Network) versions 0.100.0 through 0.101.2. The issue was discovered and disclosed on November 2, 2022, and affects the script verification system in the CKB blockchain platform (GitHub Advisory).
Technical details
The vulnerability exists in the TypeIdSystemScript resume handling mechanism when maxcycles is insufficient. Instead of properly suspending execution as expected, the system raises a ScriptError::ExceededMaximumCycles error directly. Additionally, due to the random execution order of scriptgroups, this error occurs unpredictably (GitHub Advisory).
Impact
The vulnerability can cause random failures in type_id script resume operations, potentially affecting the reliability and consistency of script execution in the CKB blockchain platform (GitHub Advisory).
Mitigation and workarounds
The vulnerability has been patched in version 0.102.0 of CKB. Users and administrators are advised to upgrade to this version or later to address the issue (GitHub Advisory).
