Test ID:	1.3.6.1.4.1.25623.1.1.10.2016.0324
Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2016-0324)
Summary:	The remote host is missing an update for the 'pdns' package(s) announced via the MGASA-2016-0324 advisory.
Description:	Summary: The remote host is missing an update for the 'pdns' package(s) announced via the MGASA-2016-0324 advisory. Vulnerability Insight: PowerDNS Authoritative Server accepts queries with a qname's length larger than 255 bytes (CVE-2016-5426). PowerDNS Authoritative Server does not properly handle dot inside labels (CVE-2016-5427). These issues allow a remote, unauthenticated attacker to cause an abnormal load on the PowerDNS backend by sending crafted DNS queries, which might result in a partial denial of service if the backend becomes overloaded. It was found that PowerDNS does not implement reasonable restrictions for zone sizes. This allows an explicitly configured primary DNS server for a zone to crash a secondary DNS server, affecting service of other zones hosted on the same secondary server (CVE-2016-6172). Affected Software/OS: 'pdns' package(s) on Mageia 5. Solution: Please install the updated package(s). CVSS Score: 7.1 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:C
