SuSE 10 Security Update : bind (ZYPP Patch Number 5409)

The transaction id and the udp source port used for DNS queries by the bind nameserver were predicatable. Attackers could potentially exploit that weakness to manipulate the DNS cache 'DNS cache poisoning', CVE-2008-1447. %NASLMINLEVEL 70300 C Tenable Network Security, Inc. The text description o...

Debian DSA-1603-1 : bind9 - DNS cache poisoning

Dan Kaminsky discovered that properties inherent to the DNS protocol lead to practical DNS cache poisoning attacks. Among other things, successful attacks can lead to misdirected web traffic and email rerouting. This update changes Debian's BIND 9 packages to implement the recommended...

DEBIAN-CVE-2008-1447

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...

DSA-1604-1 bind - DNS cache poisoning

Dan Kaminsky discovered that properties inherent to the DNS protocol lead to practical DNS cache poisoning attacks. Among other things, successful attacks can lead to misdirected web traffic and email rerouting. The BIND 8 legacy code base could not be updated to include the recommended...

FreeBSD -- DNS cache poisoning

Problem Description: The BIND DNS implementation does not randomize the UDP source port when doing remote queries, and the query id alone does not provide adequate randomization. Impact: The lack of source port randomization reduces the amount of data the attacker needs to guess in order to...

Multiple DNS implementations vulnerable to cache poisoning

Overview Deficiencies in the DNS protocol and common DNS implementations facilitate DNS cache poisoning attacks. Description The Domain Name System DNS is responsible for translating host names to IP addresses and vice versa and is critical for the normal operation of internet-connected systems...
