There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A heap-based buffer over-read exists in the function d_expression_1 in cp-demangle.c in GNU libiberty, as
    distributed in GNU Binutils 2.31.1. A crafted input can cause segmentation faults, leading to denial-of-
    service, as demonstrated by c++filt. (CVE-2018-20712)

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU
    Binutils through 2.31. There is a heap-based buffer overflow in bfd_elf32_swap_phdr_in in elfcode.h
    because the number of program headers is not restricted. (CVE-2018-19931)

  - 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)

  - The _bfd_generic_read_minisymbols function in syms.c in the Binary File Descriptor (BFD) library (aka
    libbfd), as distributed in GNU Binutils 2.31, has a memory leak via a crafted ELF file, leading to a
    denial of service (memory consumption), as demonstrated by nm. (CVE-2018-20002)

  - A heap-based buffer over-read exists in the function d_expression_1 in cp-demangle.c in GNU libiberty, as
    distributed in GNU Binutils 2.31.1. A crafted input can cause segmentation faults, leading to denial-of-
    service, as demonstrated by c++filt. (CVE-2018-20712)

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 中發布的 GNU libiberty 中，cp-demangle.c 的 d_expression_1 函式存在一個堆積型緩衝區過度讀取問題 2.31.1。特製的輸入可造成分割錯誤，進而導致拒絕服務，c++filt 即為一例。 (CVE-2018-20712)

請注意，Nessus 依賴供應商報告的套件存在。

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 2.31.1发布的 GNU libiberty 中，cp-demangle.c 的函数 d_expression_1 中存在基于堆的缓冲区过度读取。构建的输入可造成分段错误，从而导致拒绝服务，c++filt 即为一例。 (CVE-2018-20712)

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 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 で配布されている cp-demangle.c の関数 d_expression_1 に、GNU libiberty にヒープベースのバッファオーバーリードが存在します 2.31.1。細工された入力がセグメンテーション違反を引き起こし、サービス拒否を引き起こす可能性があります。これは c++filt で実証されています。 （CVE-2018-20712）

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。

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

  - A heap-based buffer over-read exists in the function d_expression_1 in cp-demangle.c in GNU libiberty, as     distributed in GNU Binutils 2.31.1. A crafted input can cause segmentation faults, leading to denial-of-     service, as demonstrated by c++filt. (CVE-2018-20712)

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