Amazon Linux 1 Security Advisory: ALAS-2015-631
Advisory Release Date: 2015-12-15 13:00 Pacific
Advisory Updated Date: 2015-12-16 20:25 Pacific
Severity:
Critical
Issue Overview:
An error in the parsing of incoming responses allows some records with an incorrect class to be be accepted by BIND instead of being rejected as malformed. This can trigger a REQUIRE assertion failure when those records are subsequently cached. Intentional exploitation of this condition is possible and could be used as a denial-of-service vector against servers performing recursive queries. (CVE-2015-8000)
CVE-2015-8461 was also issued today for bind, but the Amazon Linux AMI's version of bind is not impacted by that CVE.
Affected Packages:
bind
Issue Correction:
Run yum update bind to update your system.
