Security researchers have discovered a set of seven vulnerabilities in dnsmasq - a utility used in many Linux-based systems, especially routers and other IoT devices, to provide DNS services - which allow attackers to redirect users or execute malicious code. This dangerous set of flaws has been named DNSpooq. Patch dnsmasq now! . Security researchers have found several serious vulnerabilities in dnsmasq, a utility used in many Linux-based systems, especially routers and other IoT devices, to provide DNS services. Attackers can exploit the flaws to redirect users to rogue websites when trying to access legitimate ones or to execute malicious code on vulnerable devices. Dnsmasq is a lightweight tool that provides DNS caching, DNS forwarding and DHCP (Dynamic Host Configuration Protocol) services. The utility has been around for around 20 years and is part of the standard set of tools in many Linux distributions, including Android. As a utility that provides network services, dnsmasq is widely used in networking devices such as home business routers but is also present in many other types of embedded and IoT systems including firewalls, VoIP phones and car WiFi systems. . Critical flaws in dnsmasq place countless Linux devices at risk of exploitation. Take immediate action to protect your infrastructure!.

DNS service provider OpenDNS has announced a preview release of a new open source tool to improve internet security: DNSCrypt encrypts all DNS traffic between a user's system and a DNS server. The tool is currently only available for the Mac, with a Windows version promised, and only works with OpenDNS's own DNS service.. Normally, DNS information is exchanged between client and server as plain text which makes it vulnerable to snooping or modification and man-in-the-middle attacks. By encrypting the exchange, OpenDNS hopes to make the "last mile" of DNS requests more secure. DNS Security Extensions (DNSSEC) makes the process more secure by adding authentication to DNS communications, but does not encrypt the actual exchanges. David Ulevitch, the CEO of OpenDNS, says that DNSCrypt is designed to address that shortcoming, noting that it's an implementation of the DNSCurve forwarder concept.
