Beschreibung:	Summary: The remote host is missing an update for the 'dnsmasq' package(s) announced via the MGASA-2021-0231 advisory. Vulnerability Insight: A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier (CVE-2021-3448). This kind of configuration is the default when network-manager uses dnsmasq. Affected Software/OS: 'dnsmasq' package(s) on Mageia 7, Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
