Several vulnerabilities were fixed in elfutils, a collection of utilities and libraries to handle ELF objects.
dwarf_getaranges in dwarf_getaranges.c in libdw allowed a denial of service (heap-based buffer over-read) via a crafted file.
libelf/elf_end.c in allowed to cause a denial of service (double free and application crash) because it tried to decompress twice.
An invalid memory address dereference libdwfl allowed a denial of service (application crash) via a crafted file.
A use-after-free in recursive ELF ar files allowed a denial of service (application crash) via a crafted file.
A divide-by-zero in arlib_add_symbols() allowed a denial of service (application crash) via a crafted file.
A segmentation fault could occur due to dwfl_segment_report_module() not checking whether the dyn data read from a core file is truncated.
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.
