CVE-2020-24827
A vulnerability in the dwarf::cursor::skip_form function of Libelfin v0.3 allows attackers to cause a denial of service (DOS) through a segmentation fault via a crafted ELF file.
Does this matter?
Lower severity and a low EPSS score (0.69%). Track it; it rarely justifies an emergency change on its own.
