CVE-2023-5870

    pg_cancel_backend role can signal certain superuser processes,
    potentially resulting in denial of service.
CVE-2023-39417
    Micah Gate, Valerie Woolard, Tim Carey-Smith, and Christoph Berg
    reported that an extension script using @substitutions@ within
    quoting may allow to perform an SQL injection for an attacker having

For the oldstable distribution (bullseye), these problems have been
