The __libelf_set_rawdata_wrlock function in elf_getdata.c in elfutils before 0.168 allows remote attackers to cause a denial of service (crash) via a crafted (1) sh_off or (2) sh_size ELF header value, which triggers a memory allocation failure.

According to the versions of the elfutils packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - Elfutils is a collection of utilities, including stack     (to show backtraces), nm (for listing symbols from     object files), size (for listing the section sizes of     an object or archive file), strip (for discarding     symbols), readelf (to see the raw ELF file structures),     elflint (to check for well-formed ELF files) and     elfcompress (to compress or decompress ELF sections).
    Security Fix(es):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)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)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)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)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)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)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)**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)The
    __libelf_set_rawdata_wrlock function in elf_getdata.c     in elfutils before 0.168 allows remote attackers to     cause a denial of service (crash) via a crafted (1)     sh_off or (2) sh_size ELF header value, which triggers     a memory allocation failure.(CVE-2016-10255)
