Background ========== Net::DNS is a Perl implementation of a DNS resolver. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-perl/Net-DNS < 0.60 >= 0.60 Description =========== 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. Resolution ========== All Net::DNS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-perl/Net-DNS-0.60" References ========== [ 1 ] CVE-2007-3377 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3377 [ 2 ] CVE-2007-3409 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3409 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-06.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
