medium Nessus Plugin ID 25871

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200708-06 (Net::DNS: Multiple vulnerabilities)

 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 :

 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 :

 There is no known workaround at this time.

Solution

All Net::DNS users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=dev-perl/Net-DNS-0.60'
