MyDNS is a DNS server using a MySQL database as a backend. It is designed to allow for fast updates and small resource usage.
MyDNS contains an unspecified flaw that may allow a remote Denial of Service.
An attacker could cause a Denial of Service by sending malformed DNS queries to the MyDNS server.
There is no known workaround at this time.
All MyDNS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/mydns-1.1.0"
