请注意，Nessus 尚未测试这些问题，而是只依据应用程序自我报告的版本号进行判断。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 GNU Binutils 2.29 中发布的二进制文件描述符 (BFD) 库（又称为 libbfd）中， dwarf1.c 对指针处理不当，这可让远程攻击者通过构建的 ELF 文件，导致拒绝服务（应用程序崩溃）或可能造成其他不明影响，此问题与 parse_die 和 parse_line_table 有关，parse_die 基于堆的缓冲区过度读取即为一例。(CVE-2017-15020)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 在 GNU Binutils 2.29 發佈的二進位檔案描述元 (BFD) 程式庫 (亦稱 libbfd) 中，dwarf1.c 不當處理指標，這可允許遠端攻擊者透過特製的 ELF 檔案造成拒絕服務 (應用程式損毀)，或可能造成其他不明影響，此弱點與 parse_die 和 parse_line_table 相關，parse_die 堆積型溢位過度讀取即為一例。(CVE-2017-15020)

請注意，Nessus 依賴供應商報告的套件存在。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  -GNU Binutils 2.29で配布されているBinary File Descriptor (BFD) ライブラリ (別名libbfd) のdwarf1.cは、ポインターを誤って処理します。これにより、リモート攻撃者が細工されたELFファイルを介して、サービス拒否 (アプリケーションクラッシュ) を引き起こしたり、詳細不明な他の影響を与えたりする可能性があります。この問題は、parse_dieおよびparse_line_tableに関連しており、parse_dieのヒープベースのバッファオーバーリードが原因で発生します。(CVE-2017-15020) 

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

According to the versions of the binutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The process_version_sections function in readelf.c in     GNU Binutils 2.29 allows attackers to cause a denial of     service (Integer Overflow, and hang because of a     time-consuming loop) or possibly have unspecified other     impact via a crafted binary file with invalid values of     ent.vn_next, during 'readelf -a'     execution.(CVE-2017-14333)

  - dwarf1.c in the Binary File Descriptor (BFD) library     (aka libbfd), as distributed in GNU Binutils 2.29,     mishandles pointers, which allows remote attackers to     cause a denial of service (application crash) or     possibly have unspecified other impact via a crafted     ELF file, related to parse_die and parse_line_table, as     demonstrated by a parse_die heap-based buffer     over-read.(CVE-2017-15020)

According to the versions of the binutils package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - An integer wraparound has been discovered in the Binary     File Descriptor (BFD) library distributed in GNU     Binutils up to version 2.30. An attacker could cause a     crash by providing an ELF file with corrupted DWARF     debug information.(CVE-2018-7568)

  - A stack-based buffer overflow flaw was found in the way     various binutils utilities processed certain files. If     a user were tricked into processing a specially crafted     file, it could cause the utility used to process that     file to crash or, potentially, execute arbitrary code     with the privileges of the user running that     utility.(CVE-2014-8501)

  - The coff_slurp_line_table function in coffcode.h in the     Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.29.1, allows remote     attackers to cause a denial of service (invalid memory     access and application crash) or possibly have     unspecified other impact via a crafted PE     file.(CVE-2017-16826)

  - It was found that the fix for the CVE-2014-8485 issue     was incomplete: a heap-based buffer overflow in the     objdump utility could cause it to crash or,     potentially, execute arbitrary code with the privileges     of the user running objdump when processing specially     crafted files.(CVE-2014-8502)

  - A directory traversal flaw was found in the strip and     objcopy utilities. A specially crafted file could cause     strip or objdump to overwrite an arbitrary file     writable by the user running either of these     utilities.(CVE-2014-8737)

  - The bfd_section_from_shdr function in elf.c in the     Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, allows remote     attackers to cause a denial of service (segmentation     fault) via a large attribute section.(CVE-2018-8945)

  - In the coff_pointerize_aux function in coffgen.c in the     Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, an index is not     validated, which allows remote attackers to cause a     denial of service (segmentation fault) or possibly have     unspecified other impact via a crafted file, as     demonstrated by objcopy of a COFF     object.(CVE-2018-7208)

  - dwarf1.c in the Binary File Descriptor (BFD) library     (aka libbfd), as distributed in GNU Binutils 2.29,     mishandles pointers, which allows remote attackers to     cause a denial of service (application crash) or     possibly have unspecified other impact via a crafted     ELF file, related to parse_die and parse_line_table, as     demonstrated by a parse_die heap-based buffer     over-read.(CVE-2017-15020)

  - A buffer overflow flaw was found in the way various     binutils utilities processed certain files. If a user     were tricked into processing a specially crafted file,     it could cause the utility used to process that file to     crash or, potentially, execute arbitrary code with the     privileges of the user running that     utility.(CVE-2014-8485)

  - An integer overflow flaw was found in the way the     strings utility processed certain files. If a user were     tricked into running the strings utility on a specially     crafted file, it could cause the strings executable to     crash.(CVE-2014-8484)

  - A heap-based buffer overflow flaw was found in the way     certain binutils utilities processed archive files. If     a user were tricked into processing a specially crafted     archive file, it could cause the utility used to     process that archive to crash or, potentially, execute     arbitrary code with the privileges of the user running     that utility.(CVE-2014-8738)

  - The swap_std_reloc_in function in aoutx.h in the Binary     File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.30, allows remote     attackers to cause a denial of service     (aout_32_swap_std_reloc_out NULL pointer dereference     and application crash) via a crafted ELF file, as     demonstrated by objcopy.(CVE-2018-7642)

  - The display_debug_frames function in dwarf.c in GNU     Binutils 2.29.1 allows remote attackers to cause a     denial of service (integer overflow and heap-based     buffer over-read, and application crash) or possibly     have unspecified other impact via a crafted ELF file,     related to print_debug_frame.(CVE-2017-16828)

  - A stack-based buffer overflow flaw was found in the     SREC parser of the libbfd library. A specially crafted     file could cause an application using the libbfd     library to crash or, potentially, execute arbitrary     code with the privileges of the user running that     application.(CVE-2014-8504)

  - An integer wraparound has been discovered in the Binary     File Descriptor (BFD) library distributed in GNU     Binutils up to version 2.30. An attacker could cause a     crash by providing an ELF file with corrupted DWARF     debug information.(CVE-2018-7569)

  - A stack-based buffer overflow flaw was found in the way     objdump processed IHEX files. A specially crafted IHEX     file could cause objdump to crash or, potentially,     execute arbitrary code with the privileges of the user     running objdump.(CVE-2014-8503)

  - coffgen.c in the Binary File Descriptor (BFD) library     (aka libbfd), as distributed in GNU Binutils 2.29.1,     does not validate the symbol count, which allows remote     attackers to cause a denial of service (integer     overflow and application crash, or excessive memory     allocation) or possibly have unspecified other impact     via a crafted PE file.(CVE-2017-16831)

  - The aout_get_external_symbols function in aoutx.h in     the Binary File Descriptor (BFD) library (aka libbfd),     as distributed in GNU Binutils 2.29.1, allows remote     attackers to cause a denial of service (slurp_symtab     invalid free and application crash) or possibly have     unspecified other impact via a crafted ELF     file.(CVE-2017-16827)

  - The display_debug_ranges function in dwarf.c in GNU     Binutils 2.30 allows remote attackers to cause a denial     of service (integer overflow and application crash) or     possibly have unspecified other impact via a crafted     ELF file, as demonstrated by objdump.(CVE-2018-7643)

  - An issue was discovered in the Binary File Descriptor     (BFD) library (aka libbfd), as distributed in GNU     Binutils through 2.31. There is an integer overflow and     infinite loop caused by the IS_CONTAINED_BY_LMA macro     in elf.c.(CVE-2018-19932)
