Amit Klein of Trusteer reported that insufficient randomness is used to |
| 45 |
calculate the TRXID values and the UDP source port numbers. |

<impact type="normal"> |
| 49 |
<p> |
| 50 |
A remote attacker could send malicious answers to insert arbitrary DNS |
| 51 |
data into the cache. These attacks would in turn help an attacker to |
| 52 |
perform man-in-the-middle and site impersonation attacks. |
| 53 |

<workaround> |

There is no known workaround at this time. |

<resolution> |
