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。

  - 2018.09-rc1までのDENX U-Bootには、ファイルシステムの読み込みが誤って処理されるため、細工されたカーネルイメージを介したローカルで悪用可能なバッファオーバーフローがあります。CVE-2018-18440

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 uboot-tools package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - DENX U-Boot through 2018.09-rc1 has a locally exploitable buffer overflow via a crafted kernel image     because filesystem loading is mishandled. (CVE-2018-18440)

  - Das U-Boot 2016.11-rc1 through 2019.04 mishandles the ext4 64-bit extension, resulting in a buffer     overflow. (CVE-2019-11059)

  - gen_rand_uuid in lib/uuid.c in Das U-Boot v2014.04 through v2019.04 lacks an srand call, which allows     attackers to determine UUID values in scenarios where CONFIG_RANDOM_UUID is enabled, and Das U-Boot is     relied upon for UUID values of a GUID Partition Table of a boot device. (CVE-2019-11690)

  - A crafted self-referential DOS partition table will cause all Das U-Boot versions through 2019.07-rc4 to     infinitely recurse, causing the stack to grow infinitely and eventually either crash or overwrite other     data. (CVE-2019-13103)

  - In Das U-Boot versions 2016.11-rc1 through 2019.07-rc4, an underflow can cause memcpy() to overwrite a     very large amount of data (including the whole stack) while reading a crafted ext4 filesystem.
    (CVE-2019-13104)

  - Das U-Boot versions 2016.09 through 2019.07-rc4 can memset() too much data while reading a crafted ext4     filesystem, which results in a stack buffer overflow and likely code execution. (CVE-2019-13106)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy when parsing a UDP     packet due to a net_process_received_packet integer underflow during an nc_input_packet call.
    (CVE-2019-14192)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with an unvalidated     length at nfs_readlink_reply, in the 'if' block after calculating the new path length. (CVE-2019-14193)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length     check at nfs_read_reply when calling store_block in the NFSv2 case. (CVE-2019-14194)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with unvalidated     length at nfs_readlink_reply in the 'else' block after calculating the new path length. (CVE-2019-14195)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length     check at nfs_lookup_reply. (CVE-2019-14196)

  - An issue was discovered in Das U-Boot through 2019.07. There is a read of out-of-bounds data at     nfs_read_reply. (CVE-2019-14197)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy with a failed length     check at nfs_read_reply when calling store_block in the NFSv3 case. (CVE-2019-14198)

  - An issue was discovered in Das U-Boot through 2019.07. There is an unbounded memcpy when parsing a UDP     packet due to a net_process_received_packet integer underflow during an *udp_packet_handler call.
    (CVE-2019-14199)

  - An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this     nfs_handler reply helper function: rpc_lookup_reply. (CVE-2019-14200)

  - An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this     nfs_handler reply helper function: nfs_lookup_reply. (CVE-2019-14201)

  - An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this     nfs_handler reply helper function: nfs_readlink_reply. (CVE-2019-14202)

  - An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this     nfs_handler reply helper function: nfs_mount_reply. (CVE-2019-14203)

  - An issue was discovered in Das U-Boot through 2019.07. There is a stack-based buffer overflow in this     nfs_handler reply helper function: nfs_umountall_reply. (CVE-2019-14204)

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.

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

  - DENX U-Boot through 2018.09-rc1 has a locally exploitable buffer overflow via a crafted kernel image     because filesystem loading is mishandled. (CVE-2018-18440)
