Memory Leak found in file 'fuzz.c' in BIND-9.12.1-P2
Summary
In reviewing source code in BIND-9.12.1-P2, in directory '/bin/named', file 'fuzz.c', in function 'static void *fuzz_thread_resolver', it would appear that variable 'rbuf' is never freed prior to the function returning cleanly (i.e. - buf is released by free, but rbuf is not).
Steps to reproduce
N/A
What is the current bug behavior?
With current code, a memory leak develops over time in file 'fuzz.c'
What is the expected correct behavior?
the memory allocated for rbuf should be released before the function returns.
