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

An out-of-bounds read was discovered in elfutils in the way it reads DWARF address ranges information. Function dwarf_getaranges() in dwarf_getaranges.c does not properly check whether it reads beyond the limits of the ELF section. An attacker could use this flaw to cause a denial of service 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)

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)

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, 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.

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

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

An update of the elfutils package has been released.

Fixes CVE-2018-16062, CVE-2018-16402 and CVE-2018-16403. unstrip:
Handle SHT_GROUP sections. strip: Handle mixed (out of order) allocated/non-allocated sections. elfcompress: Don't rewrite input file if no section data needs updating. Try harder to keep same file mode bits (suid) on rewrite. libelf, libdw and all tools now handle extended shnum and shstrndx correctly.
