Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2015-1349)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
named in ISC BIND 9.7.0 through 9.9.6 before 9.9.6-P2 and 9.10.x before 9.10.1-P2, when DNSSEC validation and the managed-keys feature are enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit, or daemon crash) by triggering an incorrect trust-anchor management scenario in which no key is ready for use.
2) Input validation error (CVE-ID: CVE-2015-4620)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
name.c in named in ISC BIND 9.7.x through 9.9.x before 9.9.7-P1 and 9.10.x before 9.10.2-P2, when configured as a recursive resolver with DNSSEC validation, allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) by constructing crafted zone data and then making a query for a name in that zone.
3) Data Handling (CVE-ID: CVE-2015-5477)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
named in ISC BIND 9.x before 9.9.7-P2 and 9.10.x before 9.10.2-P3 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via TKEY queries.
4) Input validation error (CVE-ID: CVE-2015-5722)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
buffer.c in named in ISC BIND 9.x before 9.9.7-P3 and 9.10.x before 9.10.2-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) by creating a zone containing a malformed DNSSEC key and issuing a query for a name in that zone.
5) Input validation error (CVE-ID: CVE-2015-5986)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
openpgpkey_61.c in named in ISC BIND 9.9.7 before 9.9.7-P3 and 9.10.x before 9.10.2-P4 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via a crafted DNS response.
