BlueCat Networks Customers Protected from Recent DHCP Vulnerability

Toronto, Canada – December 15, 2011 – BlueCat Networks, the IPAM Intelligence™ company, recently announced the availability of a patch for its appliance-based DNS and DHCP software solutions that addresses the latest DHCP vulnerability publicized by the Internet Systems Consortium (ISC). BlueCat Networks discovered the vulnerability and was prepared to immediately provide patches to its customers on the same day as the ISC’s public release.

Working with a client, BlueCat Networks was instrumental in identifying and reporting the vulnerability (CVE-2011-4539) to the ISC. The vulnerability found by BlueCat Networks relates to a bug in the DHCP software which could allow an attacker to remotely crash a DHCP server in a Denial of Service (DoS) attack. After discovering the issue, BlueCat Networks worked with the ISC to test and verify a fix to address the vulnerability. BlueCat Networks’ proactive response demonstrates its commitment to security and providing timely patches to critical security vulnerabilities that could put organizations at risk.

“ISC is very appreciative of BlueCat Networks for its efforts in finding and testing this DHCP issue,” said Barry Greene, President of ISC. “We are committed to identifying and rapidly addressing any security vulnerabilities and look to partners like BlueCat Networks to assist us in meeting the security requirements of our customers and the Internet community at large using our Phased Disclosure Process.”

“Our customers depend on our solutions to deliver business-critical DNS and DHCP core networks services,” said Branko Miskov, Director of Product Management, BlueCat Networks. “Security is a primary focus of our organization and we have a long history of being first to market with patches to address vulnerabilities as they arise. As an early adopter and member of ISC’s ‘Friends of ISC’ program, we are one of only a handful of vendors that work directly with ISC to ensure the ongoing reliability and feature richness of BIND and DHCP.”
