Debian 10: DLA-3344-1 Critical Node.js DNS Rebinding Threat

debian lts
Calendar Grey February 26, 2023
Dist Debian Esm H88
Upgrade your Debian system by updating Node.js to mitigate DNS rebinding vulnerabilities and prevent risks of arbitrary code execution, ensuring robust security.
Vulnerabilities have been found in Node.js, which could result in DNS rebinding or arbitrary code execution

Summary

CVE-2022-43548

The Node.js rebinding protector for `--inspect` still allows invalid
IP addresses, specifically in octal format, which browsers such as
Firefox attempt to resolve via DNS. When combined with an active
`--inspect` session, such as when using VSCode, an attacker can
perform DNS rebinding and execute arbitrary code.

CVE-2023-23920

Ben Noordhuis reported that Node.js would search and potentially
load ICU data when running with elevated privileges. Node.js now
builds with `ICU_NO_USER_DATA_OVERRIDE` to avoid this.

For Debian 10 buster, these problems have been fixed in version
10.24.0~dfsg-1~deb10u3.

We recommend that you upgrade your nodejs packages.
