CVE-2018-16062

dwarf_getaranges in dwarf_getaranges.c in libdw allowed a denial of service (heap-based buffer over-read) via a crafted file.

CVE-2018-16402

libelf/elf_end.c in allowed to cause a denial of service (double free and application crash) because it tried to decompress twice.

CVE-2018-18310

An invalid memory address dereference libdwfl allowed a denial of service (application crash) via a crafted file.

CVE-2018-18520

A use-after-free in recursive ELF ar files allowed a denial of service (application crash) via a crafted file.

CVE-2018-18521

A divide-by-zero in arlib_add_symbols() allowed a denial of service (application crash) via a crafted file.

CVE-2019-7150

A segmentation fault could occur due to dwfl_segment_report_module() not checking whether the dyn data read from a core file is truncated.

CVE-2019-7665

NT_PLATFORM core notes contain a zero terminated string allowed a denial of service (application crash) via a crafted file.

For Debian 9 stretch, these problems have been fixed in version 0.168-1+deb9u1.

We recommend that you upgrade your elfutils packages.
