Detailsinfo

A vulnerability classified as critical has been found in Deno 1.32.0. Affected is an unknown part of the file read/write of the component Asynchronous Operation Handler. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Deno is a runtime for JavaScript and TypeScript that uses V8 and is built in Rust. Resizable ArrayBuffers passed to asynchronous 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. The problem has been resolved by disabling resizable ArrayBuffers temporarily in Deno 1.32.1. Deno 1.32.2 will re-enable resizable ArrayBuffers with a proper fix. As a workaround, run with `--v8-flags=--no-harmony-rab-gsab` to disable resizable ArrayBuffers.

The weakness was presented 03/24/2023 as GHSA-c25x-cm9x-qqgx. The advisory is available at github.com. This vulnerability is traded as CVE-2023-28445 since 03/15/2023. Technical details are known, but there is no available exploit.
