CVE-2016-2775 describes a denial-of-service vulnerability affecting ISC BIND versions 9.9.9-P2, 9.10.4-P2, and 9.11.0b2 and earlier, specifically when the lightweight resolver (lwresd or named lwres option) is enabled. A remote attacker can crash the daemon by sending a crafted, long request using the lightweight resolver protocol. This vulnerability carries a CVSS score of 5.9 (Medium) due to its network-based attack vector and high impact on availability, though it requires high attack complexity. While the FAUCET Risk Score is high at 90/100, there is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and it is not listed in CISA's KEV catalog. Despite this, it has garnered some community discussion and media coverage, indicating awareness within the cybersecurity landscape.
