Ubuntu 22.04 LTS / 24.04 LTS : Nix vulnerabilities (USN-7633-1)

high Nessus Plugin ID 242201

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7633-1 advisory.

 Linus Heckemann discovered that Nix did not correctly handle certain binaries. An attacker could possibly use this issue to execute arbitrary code. (CVE-2024-38531)

 Pierre-Etienne Meunier discovered that Nix did not correctly handle TLS certificates. A remote attacker could possibly use this issue to leak sensitive information. (CVE-2024-47174)

 It was discovered that Nix did not correctly handle Unix sockets. An attacker could possibly use this issue execute arbitrary code. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-27297)

 It was discovered that Nix did not correctly handle unpacking Nix archives (NARS). If a user or automated system were tricked into opening a specially crafted file, an attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2024-45593)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected nix-bin and / or nix-setup-systemd packages.
