CVE-2017-9146

The TNEFFillMapi function in lib/ytnef.c in libytnef in ytnef through 1.9.2
does not ensure a nonzero count value before a certain memory allocation,
which allows remote attackers to cause a denial of service (heap-based
buffer overflow and application crash) or possibly have unspecified other
impact via a crafted tnef file.
