CVE-2025-29087: In SQLite 3.44.0 through 3.49.0 before 3.49.1, the concat_ws() SQL function can cause memory to be written bey

Routine

LOW 3.2UPGRADE

CVE-2025-29087 is a low-severity flaw (CVSS 3.2) affecting sqlite. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

In SQLite 3.44.0 through 3.49.0 before 3.49.1, the concat_ws() SQL function can cause memory to be written beyond the end of a malloc-allocated buffer. If the separator argument is attacker-controlled and has a large string (e.g., 2MB or more), an integer overflow occurs in calculating the size of the result buffer, and thus malloc may not allocate enough memory.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

sqlite sqlite UPGRADE

Affected: >= 3.44.0 and < 3.49.1

Fixed in: 3.49.1

Safe to downgrade to: a release before 3.44.0

1. Check installed version

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

2. UPGRADE to 3.49.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sqlite

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 3.44.0 (Debian / Ubuntu)

apt-cache madison sqlite sudo apt install sqlite=<VERSION_BEFORE_3.44.0> sudo apt-mark hold sqlite

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

dnf --showduplicates list sqlite sudo dnf downgrade sqlite-<VERSION_BEFORE_3.44.0> sudo dnf versionlock add sqlite

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.
