    Package        : pgpool2
    Version        : 4.1.4-3+deb11u1
    CVE ID         : CVE-2023-22332 CVE-2024-45624

    Two vulnerabilities were discovered in pgpool2, a connection pool
    server and replication proxy for PostgreSQL.

    CVE-2023-22332

        A specific database user's authentication information may be
        obtained by another database user. As a result, the information
        stored in the database may be altered and/or database may be
        suspended by a remote attacker who successfully logged in the
        product with the obtained credentials.

    CVE-2024-45624

        When the query cache feature is enabled, it was possible that a
        database user can read rows from tables that should not be visible
        for the user through query cache.

    For Debian 11 bullseye, these problems have been fixed in version
    4.1.4-3+deb11u1.

    We recommend that you upgrade your pgpool2 packages.

    For the detailed security status of pgpool2 please refer to
    its security tracker page at:
