CVE-2018-18520

Priority
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.
