Message-ID: <CAA4i3gYx0Lc7A_mgDnt2x=w93Kx5QaLMBhirN2W3gpHu6qu-tQ@mail.gmail.com> Date: Wed, 14 Aug 2013 02:04:46 -0400 From: Roee Hay <roeeh@...ibm.com> To: bugtraq@...urityfocus.com, full-disclosure@...ts.grok.org.uk Subject: Subverting BIND's SRTT Algorithm: Derandomizing NS Selection Hi, BIND is exposed to a new vulnerability which can be exploited remotely in order to derandomize the name server selection algorithm. Exploitation of this vulnerability can be used in conjunction with other off-path DNS cache poisoning exploits in order to make them more efficient. ISC has acknowledged the vulnerability and plans to address this deficiency by re-implementing the SRTT algorithm in future maintenance releases of the BIND 9 code. Important links: 1.
