Isc · Isc Bind · CVE-2016-2848
**Name of the Vulnerable Software and Affected Versions**
ISC BIND versions 9.1.0 through 9.8.4-P2
ISC BIND versions 9.9.0 through 9.9.2-P2
**Description**
The issue allows remote attackers to cause a denial of service, resulting in an assertion failure and daemon exit, by sending a specially crafted DNS packet with malformed options data in an OPT resource record.
**Recommendations**
For versions 9.1.0 through 9.8.4-P2, update to a version later than 9.8.4-P2 to resolve the issue.
For versions 9.9.0 through 9.9.2-P2, update to a version later than 9.9.2-P2 to resolve the issue.
As a temporary workaround, consider restricting access to the DNS service to minimize the risk of exploitation.
