Net::DNS: Multiple vulnerabilities

Net::DNS: Multiple vulnerabilities Multiple vulnerabilities have been discovered in the Net::DNS Perl module, allowing for a Denial of Service and a cache poisoning attack. net-dns 2007-08-11 2007-08-11 184029 remote 0.60 0.60

Net::DNS is a Perl implementation of a DNS resolver.

hjp discovered an error when handling DNS query IDs which make them partially predictable. Steffen Ullrich discovered an error in the dn_expand() function which could lead to an endless loop.

A remote attacker could send a specially crafted DNS request to the server which could result in a Denial of Service with an infinite recursion, or perform a cache poisoning attack.

There is no known workaround at this time.

All Net::DNS users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-perl/Net-DNS-0.60"
