Published on: 13 April 2017

Description:

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

Both authoritative and recursive name servers are affected.

 

Affected Systems:

  • BIND 9.8.0 to 9.8.8-P1
  • BIND 9.9.0 to 9.9.9-P7
  • BIND 9.9.3-S1 to 9.9.9-S9
  • BIND 9.9.10b1 to 9.9.10rc2
  • BIND 9.10.0 to 9.10.4-P7
  • BIND 9.10.5b1 to 9.10.5rc2
  • BIND 9.11.0 to 9.11.0-P4
  • BIND 9.11.1b1 to 9.11.1rc2

 

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-P8, 9.10.4-P8 and 9.11.0-P5
  • BIND v9.9.9-S10
  • BIND 9.9.10rc3, 9.10.5rc3 and 9.11.1rc3
