| isc-bind-acl-security-bypass (35571) |  Medium Risk |
Description:
ISC BIND could allow a remote attacker to bypass security restrictions. The default ACL is improperly set and allows an attacker to query cache contents or to send recursive queries. A remote attacker could exploit this vulnerability to bypass security restrictions and obtain sensitive information.
