The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has elfutils packages installed that are affected by multiple vulnerabilities:

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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, 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)

  - **DISPUTED** 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)

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