Description

An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.
