Detail
A certain pseudo-random number generator (PRNG) algorithm that uses XOR and 3-bit random hops (aka "Algorithm X3"), as used in OpenBSD 2.8 through 4.2, allows remote attackers to guess sensitive values such as DNS transaction IDs by observing a sequence of previously generated values. NOTE: this issue can be leveraged for attacks such as DNS cache poisoning against OpenBSD's modification of BIND. |

Id | Description |
---|---|
41143 | OpenBSD DNS Server PRNG Transaction ID Disclosure Cache Poisoning OpenBSD contains a flaw that may allow a malicious user to poison a recursive DNS cache. The issue is triggered by a weakness in the X3 algorithm used to generate random DNS transaction IDs, which combined with a static source port for all DNS queries can allow an attacker to spoof a DNS response packet. It is possible that the flaw may allow a remote attacker to poison a DNS cache resulting in a loss of integrity. |
