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.

Affected configurations

• elfutils project elfutils (<= 0.174) • debian debian linux 8.0 • debian debian linux 9.0 • canonical ubuntu linux 16.04 • canonical ubuntu linux 18.04 • canonical ubuntu linux 18.10 • opensuse leap 15.0 • opensuse leap 15.1 • redhat enterprise linux desktop 7.0 • redhat enterprise linux server 7.0 • redhat enterprise linux workstation 7.0
