MEDIUM 6.5REMOTEUPGRADE

CVE-2025-64429 is a medium-severity flaw (CVSS 6.5) affecting duckdb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

DuckDB is a SQL database management system. DuckDB implemented block-based encryption of DB on the filesystem starting with DuckDB 1.4.0. There are a few issues related to this implementation. The DuckDB can fall back to an insecure random number generator (pcg32) to generate cryptographic keys or IVs. When clearing keys from memory, the compiler may remove the memset() and leave sensitive data on the heap. By modifying the database header, an at

duckdb duckdb UPGRADE

Affected: >= 1.4.0 and < 1.4.2

Fixed in: 1.4.2

Safe to downgrade to: a release before 1.4.0

1. Check installed version

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

2. UPGRADE to 1.4.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade duckdb

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 1.4.0 (Debian / Ubuntu)

apt-cache madison duckdb sudo apt install duckdb=<VERSION_BEFORE_1.4.0> sudo apt-mark hold duckdb

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

dnf --showduplicates list duckdb sudo dnf downgrade duckdb-<VERSION_BEFORE_1.4.0> sudo dnf versionlock add duckdb

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.
