CVE-2016-8687
Stack-based buffer overflow in the safe_fprintf function in tar/util.c in libarchive 3.2.1 allows remote attackers to cause a denial of service via a crafted non-printable multibyte character in a filename.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.26%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
