Description

This security bulletin contains information about 1 vulnerability.


1) Exposure of Resource to Wrong Sphere (CVE-ID: CVE-2024-27935)

The vulnerability allows a remote attacker to disclose sensitive information and cause data corruption.

The vulnerability exists due to improper isolation of a global buffer in stream_wrap.ts in Deno's Node.js compatibility runtime when performing simultaneous asynchronous reads from Node.js streams sourced from sockets or files. A remote attacker can trigger concurrent stream reads to disclose sensitive information and cause data corruption.

The issue does not affect network streams created with the Deno.listen and Deno.connect APIs.
