Name of the Vulnerable Software and Affected Versions nginx versions 1.8.0 through 1.8.1 nginx versions 1.9.x through 1.9.10

Description The issue in the resolver of nginx allows remote attackers to cause a denial of service, resulting in an invalid pointer dereference and worker process crash, via a crafted UDP DNS response.

Recommendations For nginx versions 1.8.0 through 1.8.1, update to version 1.8.1 or later. For nginx versions 1.9.x through 1.9.10, update to version 1.9.10 or later. As a temporary workaround, consider restricting access to UDP DNS responses to minimize the risk of exploitation.
