CVE-2018-13844
It is a memory leak in fai_read in faidx.c.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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
