Widely used DNS server software - BIND is under attacked to cause disruption in the internet service for many users. The BIND versions 9.1.0 to 9.10.2-P2 are affected and can be exploited to crash DNS servers that are powered by the software. Internet Systems Consortium (ISC) has released a patch to rectify this critical issue that affects both authoritative and recursive DNS servers with a single packet. ISP configures recursive DNS servers for most computers and routers.

According to ISC advisory, patching is the only available option so operators are required to apply the security patch as early as possible. <more>
