- Update to 2.83: * bsc#1177077: Fixed DNSpooq vulnerabilities * Use the values of --min-port and --max-port in outgoing TCP connections to upstream DNS servers. * Fix a remote buffer overflow problem in the DNSSEC code. Any dnsmasq with DNSSEC compiled in and enabled is vulnerable to this, referenced by CVE-2020-25681, CVE-2020-25682, CVE-2020-25683 CVE-2020-25687. * Be sure to only accept UDP DNS query replies at the address from which the query was originated. This keeps as much entropy in the {query-ID, random-port} tuple as possible, to help defeat cache poisoning attacks. Refer: CVE-2020-25684. * Use the SHA-256 hash function to verify that DNS answers received are for the questions originally asked. This replaces the slightly insecure SHA-1 (when compiled with DNSSEC) or the very insecure CRC32 (otherwise). Refer: CVE-2020-25685 * Handle multiple identical near simultaneous DNS queries better. Previously, such queries would all be forwarded independently. This is, in theory, inefficent but in practise not a problem, _except_ that is means that an answer for any of the forwarded queries will be accepted and cached. An attacker can send a query multiple times, and for each repeat, another {port, ID} becomes capable of accepting the answer he is sending in the blind, to random IDs and ports. The chance of a succesful attack is therefore multiplied by the number of repeats of the query. The new behaviour detects repeated queries and merely stores the clients sending repeats so that when the first query completes, the answer can be sent to all the clients who asked. Refer: CVE-2020-25686. OBS-URL: https://build.opensuse.org/package/show/network/dnsmasq?expand=0&rev=126

%description
Dnsmasq provides network infrastructure for small networks: DNS,
DHCP, router advertisement and network boot.
The DNS subsystem supprots forwarding of all query types, and caching
of common record types, DNSSEC included. The DHCP subsystem supports
DHCPv4, DHCPv6, BOOTP and PXE. RA can be used stand-alone or in
conjunction with DHCPv6.
