Dear user,

Please find below a security advisory, relating to PowerDNS Recursor
4.8.7, 4.9.4 and 5.0.3 only.

When using recursive forwarding, a crafted response from an upstream
server can cause a Denial of Service in the Recursor.

=========================================================================
PowerDNS Security Advisory 2024-02: if recursive forwarding is
configured, crafted responses can lead to a denial of service in Recursor

    CVE: CVE-2024-25583
    Date: 24th of April 2024.
    Affects: PowerDNS Recursor 4.8.7, 4.9.4 and 5.0.3, earlier versions
are not affected
    Not affected: PowerDNS Recursor 4.8.8, 4.9.5 and 5.0.4
    Severity: High (only when using recursive forwarding)
    Impact: Denial of service
    Exploit: This problem can be triggered by an attacker publishing a crafted zone
    Risk of system compromise: None
    Solution: Upgrade to patched version

When using recursive forwarding, a crafted response from an upstream
server can cause a Denial of Service in the Recursor. The default
configuration of the Recursor does not use recursive forwarding and is
not affected.

CVSS Score: 7.5, only for configurations using recursive forwarding, see
https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator?vector=AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H&version=3.1

The remedy is to update to a patched version.
