| <affected> |
| <package name="dev-perl/Net-DNS" auto="yes" arch="*"> |
| <unaffected range="ge">0.60</unaffected> |

| <background> |
| <p> |
| Net::DNS is a Perl implementation of a DNS resolver. |
| </p> |
| </background> |
| <description> |
| <p> |
| 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. |
| </p> |
| </description> |
| <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. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Net::DNS users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-perl/Net-DNS-0.60"</code> |
| </resolution> |
