ISC BIND rdata denial of service

isc-bind-rdata-dos (76034) The risk level is classified as MediumMedium Risk

Description:

ISC BIND is vulnerable to a denial of service, caused by an error when handling DNS resource records. A remote attacker could exploit this vulnerability via records containing zero length rdata to cause recursive servers to crash or obtain sensitive information.

*CVSS:

Base Score: 5
  Access Vector: Network
  Access Complexity: Low
  Authentication: None
  Confidentiality Impact: None
  Integrity Impact: None
  Availability Impact: Partial
 
Temporal Score: 3.7
  Exploitability: Unproven
  Remediation Level: Official-Fix
  Report Confidence: Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of ISC BIND (9.6-ESV-R7-P1, 9.7.6-P1, 9.8.3-P1, or 9.9.1-P1 or later), available from the Internet Software Consortium (ISC) Web site. See References.
