CVE-2018-20451
The process_file function in reader.c in libdoc through 2017-10-23 has a heap-based buffer over-read that allows attackers to cause a denial of service (application crash) via a crafted file.
Does this matter?
Lower severity and a low EPSS score (0.94%). Track it; it rarely justifies an emergency change on its own.
