Published on: 12 January 2017

Description:

Multiple vulnerabilities were found in the ISC BIND software. A remote attacker could send a specially crafted query to trigger an assertion failure which could cause the BIND to exit.

Both authoritative and recursive name servers are affected. 

 

Affected Systems:

  • BIND 9.4.0 to 9.6-ESV-R11-W1
  • BIND 9.8.5 to 9.8.8
  • BIND 9.9.3 to 9.9.9-P4
  • BIND 9.9.8-S1 to 9.9.8-S3
  • BIND 9.9.9-S1 to 9.9.9-S6
  • BIND 9.10.0 to 9.10.4-P4
  • BIND 9.11.0 to 9.11.0-P1

 

Impact:

 Successful exploitation could lead to a denial of service (DoS) condition on an affected system.

 

Recommendation:

Internet Systems Consortium (ISC) has released the following patches to solve the problems:

  • BIND 9.9.9-P5, 9.10.4-P5 and 9.11.0-P2
  • BIND 9.9.9-S7
