Description

DNS contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when the host's DNS name server allows zone transfers to replicate zone information between master and slave DNS servers. If zone transfers have not been restricted to authorized slave servers only, a remote attacker could disclose sensitive network information resulting in a loss of confidentiality.
