CVE-2023-28445 Open this link in a new tabHow to fix?
Upgrade deno to version 1.32.1 or higher.
Overview
deno is an a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.
Affected versions of this package are vulnerable to Out-of-bounds Write due to improperly handling resizable ArrayBuffer, when passing Resizable ArrayBuffers to asynchronous native functions that are shrunk during the asynchronous operation.
Note: Deno Deploy users are not affected.
The problem has been temporarily resolved by disabling resizable ArrayBuffers in Deno 1.32.1.
Workaround
Users who are unable to upgrade to the fixed version can run with --v8-flags=--no-harmony-rab-gsab to disable resizable ArrayBuffers.
