DEBIAN-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...

CVE-2008-1637

CVE-2008-1637 affects the PowerDNS Recursor (3.x) prior to 3.1.6, due to insufficient randomness used to compute TRXID values and UDP source ports, enabling potential cache poisoning. The underlying issue involves weaknesses in the random/seeding approach (32-bit seed; time-based seeding; externa...

Paper by Amit Klein (Trusteer): "PowerDNS Recursor DNS Cache Poisoning [pharming]"

Hello BugTraq Once again, a DNS cache poisoning against a popular DNS cache server. This time, it's PowerDNS the third most popular DNS server, servicing over 40 million users. The vendor coded several impressive security measures against DNS spoofing e.g. UDP source port randomization and spoofe...

powerdns-recursor -- DNS cache poisoning

If the system random number generator can be predicted by its past output, then an attacker may spoof Recursor to accept mallicious data. This leads to DNS cache poisoning and client redirection...

A paper by Amit Klein (Trusteer): "OpenBSD DNS Cache Poisoning and Multiple O/S Predictable IP ID Vulnerability"

Hello BugTraq Recently I've been looking at the OpenBSD PRNG implementation for DNS transaction ID OpenBSD ported BIND 9 into their code tree, but rolled their own PRNG for the DNS transaction ID field. I discovered a serious weakness in OpenBSD's PRNG, which allows an attacker to predict the nex...
