+ <title>Net::DNS: Multiple vulnerabilities</title>
+ <synopsis>
+ Multiple vulnerabilities have been discovered in the Net::DNS Perl module,
+ allowing for a Denial of Service and a cache poisoning attack.

+ <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 "&gt;=dev-perl/Net-DNS-0.60"</code>
+ </resolution>
