In SQLite 3.49.0 before 3.49.1, certain argument values to sqlite3_db_config (in the C-language API) can cause a denial of service (application crash). An sz*nBig multiplication is not cast to a 64-bit integer, and consequently some memory allocations may be incorrect.

sqlite sqlite DOWNGRADE

Affected: 3.49.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.49.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.49.0 (Debian / Ubuntu)

apt-cache madison sqlite sudo apt install sqlite=<VERSION_BEFORE_3.49.0> sudo apt-mark hold sqlite

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list sqlite sudo dnf downgrade sqlite-<VERSION_BEFORE_3.49.0> 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.
