hjp discovered an error when handling DNS query IDs which make them
|
||
|
|
partially predictable. Steffen Ullrich discovered an error in the
|
||
|
|
dn_expand() function which could lead to an endless loop.

<impact type="normal">
|

|
|
<p>
|
||
|
|
A remote attacker could send a specially crafted DNS request to the
|
||
|
|
server which could result in a Denial of Service with an infinite
|
||
|
|
recursion, or perform a cache poisoning attack.
|

<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.

<resolution>
|

|

<p>
|

|
|
All Net::DNS users should upgrade to the latest version:

|
|

<code>
|

|
|
# emerge --sync
|

|

# emerge --ask --oneshot --verbose ">=dev-perl/Net-DNS-0.60"</code>
