CRITICAL 9.8REMOTEWATCHLISTUPGRADE

CVE-2024-52338 is a critical-severity flaw (CVSS 9.8) affecting arrow. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Deserialization of untrusted data in IPC and Parquet readers in the Apache Arrow R package versions 4.0.0 through 16.1.0 allows arbitrary code execution. An application is vulnerable if it reads Arrow IPC, Feather or Parquet data from untrusted sources (for example, user-supplied input files). This vulnerability only affects the arrow R package, not other Apache Arrow implementations or bindings unless those bindings are specifically used via

apache arrow UPGRADE

Affected: >= 4.0.0 and < 17.0.0

Fixed in: 17.0.0

Safe to downgrade to: a release before 4.0.0

1. Check installed version

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

2. UPGRADE to 17.0.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade arrow

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 4.0.0 (Debian / Ubuntu)

apt-cache madison arrow sudo apt install arrow=<VERSION_BEFORE_4.0.0> sudo apt-mark hold arrow

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

dnf --showduplicates list arrow sudo dnf downgrade arrow-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add arrow

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.
