Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3670-1 advisory.

    Agostino Sarubbo discovered that elfutils incorrectly handled certain malformed ELF files. If a user or     automated system were tricked into processing a specially crafted ELF file, elfutils could be made to     crash or consume resources, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2614-1 advisory.

  - The handle_gnu_hash function in readelf.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-2017-7607)

  - The ebl_object_note_type_name function in eblobjnotetypename.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-2017-7608)

  - 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.
