Package : nodejs
Version : 10.24.0~dfsg-1~deb10u3
CVE ID : CVE-2022-43548 CVE-2023-23920
Debian Bug : 1023518 1031834

Vulnerabilities have been found in Node.js, which could result in DNS
rebinding or arbitrary code execution.

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.
