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.
