DNSmasq sort_rrset Heap OOB Write

This strike simulates a heap out-of-bounds write vulnerability in DNSmasq. The vulnerability is due to no string null byte check when sorting RR records in the sort_rrset() function. Successful exploitation may result in arbitrary code execution with privileges of the DNSmasq process, or abnormal termination of the DNSmasq process, resulting in a denial of service condition.
