ruby -- DNS spoofing vulnerability

The official ruby site reports: resolv.rb allow remote attackers to spoof DNS answers. This risk can be reduced by randomness of DNS transaction IDs and source ports...

DEBIAN-CVE-2008-3217

PowerDNS Recursor before 3.1.6 does not always use the strongest random number generator for source port selection, which makes it easier for remote attack vectors to conduct DNS cache poisoning. NOTE: this is related to incomplete integration of security improvements associated with addressing...

The DNS protocol, as implemented in 1 BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; 2 Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referral...

ruby -- DNS spoofing vulnerability in resolv.rb

resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7 before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential transaction IDs and constant source ports for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than...

ruby - DNS spoofing vulnerability in resolv.rb

resolv.rb allow remote attackers to spoof DNS answers. This risk can be reduced by randomness of DNS transaction IDs and source ports, so resolv.rb is fixed to randomize them...

PowerDNS Recursor: DNS Cache Poisoning

Background The PowerDNS Recursor is an advanced recursing nameserver. Description Amit Klein of Trusteer reported that insufficient randomness is used to calculate the TRXID values and the UDP source port numbers CVE-2008-1637. Thomas Biege of SUSE pointed out that a prior fix to resolve this iss...

CVE-2008-1637

PowerDNS Recursor before 3.1.5 uses insufficient randomness to calculate 1 TRXID values and 2 UDP source port numbers, which makes it easier for remote attackers to poison a DNS cache, related to a algorithmic deficiencies in rand and random functions in external libraries, b use of a 32-bit seed...
