GLSA-200708-06 : Net::DNS: Multiple vulnerabilities

Medium Nessus Plugin ID 25871


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


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.


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