Description

An issue was discovered in the autorand crate before 0.2.3 for Rust. Because of impl Random on arrays, uninitialized memory can be dropped when a panic occurs, leading to memory corruption.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for autorand, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update autorand to 0.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2020-36210 is resolved across your whole dependency graph.

  3. Workarounds

    Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.
