CVE-2023-28445 — Vulnerability in Deno — CVE Details

CRITICAL

Deno improperly handles resizable ArrayBuffer

Published March 23, 2023Updated November 8, 2023Source: osv

Summary

### Impact [Resizable ArrayBuffers](https://github.com/tc39/proposal-resizablearraybuffer) passed to asynchronous native functions that are shrunk during the asynchronous operation could result in an out-of-bound read/write. It is unlikely that this has been exploited in the wild, as the only version affected is Deno 1.32.0. Deno Deploy users are not affected. ### Patches The problem has been resolved by disabling resizable ArrayBuffers temporarily in Deno 1.32.1. A future version of Deno will re-enable resizable ArrayBuffers with a proper fix. ### Workarounds Upgrade to Deno 1.32.1, or run with `--v8-flags=--no-harmony-rab-gsab` to disable resizable ArrayBuffers.
