File main/dns_core.c:

https://gerrit.asterisk.org/#/c/7667/1/main/dns_core.c@450
PS1, Line 450: static struct ast_dns_record *allocate_dns_record(int rr_type, struct ast_dns_query *query, const char *data, const size_t size)
To be pedantic, negative values of rr_type will also access outside of the array.  Simply change rr_type to unsigned int or test for non-negative values.
