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 20160923 之前的 libdwarf 中，_dwarf_calculate_info_section_end_ptr 函数可让远程攻击者通过特制的文件造成拒绝服务（空指针取消引用）。 (CVE-2016-5030)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

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

  - The _dwarf_calculate_info_section_end_ptr function in libdwarf before 20160923 allows remote attackers to     cause a denial of service (NULL pointer dereference) via a crafted file. (CVE-2016-5030)

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

Christian Rebischke reports :

libdwarf is vulnerable to multiple issues including arbitrary code execution, information disclosure and denial of service.

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。

  - 20160923より前のlibdwarfにある_dwarf_calculate_info_section_end_ptr関数により、リモートの攻撃者が細工されたファイルを介してサービス拒否（NULLポインターデリファレンス）を引き起こす可能性があります。 （CVE-2016-5030）

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。

Christian Rebischkeによる報告: 

libdwarfは、任意のコードの実行、情報漏洩、サービス拒否といった複数の問題に対して脆弱です。
