Amazon Linux 1 Security Advisory: ALAS-2012-84
Advisory Release Date: 2012-06-10 11:47 Pacific
Advisory Updated Date: 2014-09-14 16:18 Pacific
Severity: Important
Issue Overview:

A flaw was found in the way BIND handled zero length resource data records. A malicious owner of a DNS domain could use this flaw to create specially-crafted DNS resource records that would cause a recursive resolver or secondary server to crash or, possibly, disclose portions of its memory. (CVE-2012-1667)

A flaw was found in the way BIND handled the updating of cached name server (NS) resource records. A malicious owner of a DNS domain could use this flaw to keep the domain resolvable by the BIND server even after the delegation was removed from the parent DNS zone. With this update, BIND limits the time-to-live of the replacement record to that of the time-to-live of the record being replaced. (CVE-2012-1033)
