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.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
