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...

Debian DSA-1544-2 : pdns-recursor - design flaw

Amit Klein discovered that pdns-recursor, a caching DNS resolver, uses a weak random number generator to create DNS transaction IDs and UDP source port numbers. As a result, cache poisoning attacks were simplified. CVE-2008-1637 and CVE-2008-3217 %NASLMINLEVEL 70300 C Tenable Network Security, In...

FreeBSD : powerdns-recursor -- DNS cache poisoning (b21790a5-02fb-11dd-bd06-0017319806e7)

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. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The descriptive text and package checks in this...

Microsoft Windows DNS Stub Resolver Cache Poisoning (MS08-020)

Hello BugTraq, The Microsoft Windows DNS stub resolver the component in Windows that queries the upstream DNS server for address resolutions on behalf of most Windows programs, e.g. browsers sends predictable DNS queries with respect to DNS transaction ID and source UDP port. This allows some...

CVE-2008-1637

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...
