CVE-2017-9146 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.39% chance of exploitation in the next 30 days.
