CVE-2012-1667

35
FAUCET Score

CVE-2012-1667 is a critical vulnerability affecting multiple versions of ISC BIND 9.x, including 9.7.6-P1, 9.8.3-P1, 9.9.1-P1, and specific 9.4-ESV and 9.6-ESV releases. This flaw arises from improper handling of resource records with zero-length RDATA sections, allowing remote DNS servers to trigger a denial of service (daemon crash or data corruption) or information disclosure. With a CVSS score of 8.5, it presents a high-severity risk due to its network-based attack vector and low attack complexity, potentially leading to significant service disruption or sensitive data exposure. Despite its high FAUCET Risk Score of 97/100 and above-average EPSS, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
