NVD Description

Note: Versions mentioned in the description apply only to the upstream elfutils-libelf package and not the elfutils-libelf package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

Integer overflow in the check_section function in dwarf_begin_elf.c in the libdw library, as used in elfutils 0.153 and possibly through 0.158 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed compressed debug section in an ELF file, which triggers a heap-based buffer overflow.
