    (CVE-2017-7608)

  - elf_compress.c in elfutils 0.168 does not validate the zlib compression factor, which allows remote     attackers to cause a denial of service (memory consumption) via a crafted ELF file. (CVE-2017-7609)

  - The check_group function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of     service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7610)

  - The check_symtab_shndx function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial     of service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7611)

  - The check_sysv_hash function in elflint.c in elfutils 0.168 allows remote attackers to cause a denial of     service (heap-based buffer over-read and application crash) via a crafted ELF file. (CVE-2017-7612)

  - elflint.c in elfutils 0.168 does not validate the number of sections and the number of segments, which     allows remote attackers to cause a denial of service (memory consumption) via a crafted ELF file.
    (CVE-2017-7613)

  - dwarf_getaranges in dwarf_getaranges.c in libdw in elfutils before 2018-08-18 allows remote attackers to     cause a denial of service (heap-based buffer over-read) via a crafted file. (CVE-2018-16062)

  - libelf/elf_end.c in elfutils 0.173 allows remote attackers to cause a denial of service (double free and     application crash) or possibly have unspecified other impact because it tries to decompress twice.
    (CVE-2018-16402)

  - libdw in elfutils 0.173 checks the end of the attributes list incorrectly in dwarf_getabbrev in     dwarf_getabbrev.c and dwarf_hasattr in dwarf_hasattr.c, leading to a heap-based buffer over-read and an     application crash. (CVE-2018-16403)

  - An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in     elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application     crash) with a crafted ELF file, as demonstrated by consider_notes. (CVE-2018-18310)

  - 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. (CVE-2018-18520)

  - Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow     remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated     by eu-ranlib, because a zero sh_entsize is mishandled. (CVE-2018-18521)

  - In elfutils 0.175, there is a buffer over-read in the ebl_object_note function in eblobjnote.c in libebl.
    Remote attackers could leverage this vulnerability to cause a denial-of-service via a crafted elf file, as     demonstrated by eu-readelf. (CVE-2019-7146)

  - An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in     libelf in elfutils 0.174. Remote attackers could leverage this vulnerability to cause a denial-of-service     via crafted elf input, which leads to an out-of-memory exception. NOTE: The maintainers believe this is     not a real issue, but instead a warning caused by ASAN because the allocation is big. By setting     ASAN_OPTIONS=allocator_may_return_null=1 and running the reproducer, nothing happens. (CVE-2019-7148)

  - A heap-based buffer over-read was discovered in the function read_srclines in dwarf_getsrclines.c in libdw     in elfutils 0.175. A crafted input can cause segmentation faults, leading to denial-of-service, as     demonstrated by eu-nm. (CVE-2019-7149)

  - An issue was discovered in elfutils 0.175. A segmentation fault can occur in the function elf64_xlatetom     in libelf/elf32_xlatetom.c, due to dwfl_segment_report_module not checking whether the dyn data read from     a core file is truncated. A crafted input can cause a program crash, leading to denial-of-service, as     demonstrated by eu-stack. (CVE-2019-7150)

  - In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of     an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service     (program crash). (CVE-2019-7664)

  - In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in     elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of     service (program crash) because ebl_core_note does not reject malformed core file notes. (CVE-2019-7665)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
