Summary

ELFIO through 3.12 contains a NULL pointer dereference vulnerability in relocation_section_accessor get_entry() that allows attackers to crash applications via an unvalidated sh_link index. Attackers can supply a crafted ELF file whose SHT_REL or SHT_RELA section has a dangling sh_link, causing find_hash_section() to dereference null and deny service.

Risk Assessment

A crafted ELF file can crash the application processing binary files, leading to denial of service.

Recommendation

Upgrade ELFIO beyond version 3.12 or avoid processing untrusted ELF files until a fix is released.
