What is CVE-2023-28445?

A vulnerability in the Deno Runtime, specifically affecting version 1.32.0, arises from the use of resizable ArrayBuffers in asynchronous functions. When these ArrayBuffers are shrunk during an asynchronous operation, it can lead to out-of-bounds read/write scenarios, posing potential risks to application integrity. Users of Deno Deploy remain unaffected by this issue. In response, Deno version 1.32.1 disables the problematic feature as a temporary measure, while version 1.32.2 aims to reintroduce resizable ArrayBuffers with a proper fix. For urgent implementations, users can run Deno with the flag '--v8-flags=--no-harmony-rab-gsab' to mitigate risks.
