Advisory Updated Date: 2015-09-02 13:05 Pacific
Severity:
Critical
References:
CVE-2015-5722
Issue Overview:
As <a href="https://kb.isc.org/article/AA-01287/0">discussed upstream</a>, parsing a malformed DNSSEC key can cause a validating resolver to exit due to a failed assertion in buffer.c. It is possible for a remote attacker to deliberately trigger this condition, for example by using a query which requires a response from a zone containing a deliberately malformed key. (CVE-2015-5722)
Also <a href="https://kb.isc.org/article/AA-01291/0">disclosed upstream</a> today was CVE-2015-5986 which does not impact the version of bind in the Amazon Linux AMI.
