CVE-2010-2947
Heap-based buffer overflow in the HX_split function in string.c in libHX before 3.6 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a string that is inconsistent with the expected number of fields.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
