Summary
bind9 vulnerabilities
Details

Zuyao Xu and Xiang Li discovered that Bind incorrectly handled certain malformed DNSKEY records. A remote attacker could possibly use this issue to cause Bind to consume resources, resulting in a denial of service. (CVE-2025-8677)

Yuxiao Wu, Yunyi Zhang, Baojun Liu, and Haixin Duan discovered that Bind incorrectly accepted certain records from answers. A remote attacker could possibly use this issue to perform a cache poisoning attack. (CVE-2025-40778)

Amit Klein and Omer Ben Simhon discovered that Bind used a weak PRNG. A remote attacker could possibly use this issue to perform a cache poisoning attack. (CVE-2025-40780)
