CRITICAL 10.0REMOTEWATCHLISTUPGRADEMITIGATE

CVE-2024-42472 is a critical-severity flaw (CVSS 10.0) affecting flatpak, debian linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.14.0 and 1.15.10, a malicious or compromised Flatpak app using persistent directories could access and write files outside of what it would otherwise have access to, which is an attack on integrity and confidentiality. When `persistent=subdir` is used in the application permissions (represented as `--persist=subdir` in the command-line interface), that mean

flatpak flatpak UPGRADE

Affected: >= 1.14.0 and < 1.14.10 · >= 1.15.0 and < 1.15.10

Fixed in: 1.14.10, 1.15.10

Safe to downgrade to: a release before 1.14.0

1. Check installed version

apt-cache policy flatpak || rpm -q flatpak || flatpak --version

2. UPGRADE to 1.14.10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade flatpak

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade flatpak

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.14.0 (Debian / Ubuntu)

apt-cache madison flatpak sudo apt install flatpak=<VERSION_BEFORE_1.14.0> sudo apt-mark hold flatpak

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list flatpak sudo dnf downgrade flatpak-<VERSION_BEFORE_1.14.0> sudo dnf versionlock add flatpak

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.

debian debian linux MITIGATE

Affected: 11.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 11.0

Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Windows

Install the latest cumulative update from Windows Update

If no patch exists yet

OS downgrades are not safe. Apply the vendor mitigation from the advisory and restrict exposure.

Exact fixes by distribution

A distro patch exists: prefer upgrading over downgrading.
