** DISPUTED ** An issue has been found in HTSlib 1.8. It is a memory leak in fai_read in faidx.c. NOTE: This has been disputed with the assertion that this vulnerability exists in the test harness and HTSlib users would be aware of the need to destruct this object returned by fai_load() in their own code.


Fix was done in test code. Since the test is only available in
htslib >= 1.8, then marking as not affected in earlier versions
of htslib
