CVE-2018-18520: Buffer Overflow
First published: Fri Oct 19 2018(Updated: )
A flaw was found in elfutils through v0.174. An Invalid Memory Address Dereference exists in the function elf_end in libelf. 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.
