CVE-2017-9847
The bdecode function in bdecode.cpp in libtorrent 1.1.3 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted file.
Does this matter?
Lower severity and a low EPSS score (1.06%). Track it; it rarely justifies an emergency change on its own.
