CVE-2014-9862
Integer signedness error in bspatch.c in bspatch in bsdiff, as used in Apple OS X before 10.11.6 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (heap-based buffer overflow) via a crafted patch file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
