Vulnerability Details

CVEID: CVE-2017-3136**
DESCRIPTION:** ISC BIND is vulnerable to a denial of service, caused by the improper handling of query requests when using DNS64 with “break-dnssec yes” option. By sending a specially crafted DNS request, a remote attacker could exploit this vulnerability to make named exit unexpectedly with an assertion failure.
CVSS Base Score: 5.9

CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2017-3137**
DESCRIPTION:** ISC BIND is vulnerable to a denial of service, caused by the improper handling of a query response containing CNAME or DNAME resource records in an unusual order. By sending a specially crafted DNS response, a remote attacker could exploit this vulnerability to make named exit unexpectedly with an assertion failure.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/124517 for the current score
CVSS Environmental Score*: Undefined

CVEID: CVE-2017-3138**
DESCRIPTION:** ISC BIND is vulnerable to a denial of service, caused by an error related to the processing of control channel commands. By sending a specially crafted command, a remote attacker with access to the BIND control channel could exploit this vulnerability to make named exit unexpectedly with an assertion failure.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/124518 for the current score

CVE-ID:CVE-2017-3142
DESCRIPTION: ISC BIND could allow a remote attacker to bypass security restrictions, caused by an error when an attacker can send and receive messages to an authoritative DNS server and has knowledge of a valid TSIG key name. By sending a specially crafted request packet, an attacker could exploit this vulnerability to bypass TSIG authentication on AXFR requests and transfer the target zone.

CVE-ID:CVE-2017-3143
DESCRIPTION: ISC BIND could allow a remote attacker to bypass security restrictions, caused by an error when an attacker can send and receive messages to an authoritative DNS server and has knowledge of a valid TSIG key name. By sending specially crafted data, an attacker could exploit this vulnerability to bypass TSIG authentication and manipulate BIND into accepting an unauthorized dynamic update.
