Headline
GHSA-c25x-cm9x-qqgx: Deno improperly handles resizable ArrayBuffer
Impact
Resizable ArrayBuffers 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. Deno 1.32.2 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.
