CVE-2023-28445

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.

Remediation

Upgrade to the fixed version using your package manager.

Cargo
Update Deno to 1.32.1 or later
cargo update -p Deno --precise 1.32.1
Cargo
Update deno_runtime to 0.103.0 or later
cargo update -p deno_runtime --precise 0.103.0
Cargo
Update serde_v8 to 0.88.0 or later
cargo update -p serde_v8 --precise 0.88.0

After upgrading, run your dependency scanner again to confirm the vulnerability is resolved.
