The version of ntfs-3g installed on the remote host is prior to 2021.8.22. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2021-243-01 advisory.

  • A crafted NTFS image can trigger a heap-based buffer overflow, caused by an unsanitized attribute in ntfs_get_attribute_value, in NTFS-3G < 2021.8.22. (CVE-2021-39263)

  • In NTFS-3G versions < 2021.8.22, when a specially crafted unicode string is supplied in an NTFS image a heap buffer overflow can occur and allow for code execution. (CVE-2021-33286)

  • In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function ntfs_attr_pread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of service of the application. (CVE-2021-33287)

  • In NTFS-3G versions < 2021.8.22, when a specially crafted MFT section is supplied in an NTFS image a heap buffer overflow can occur and allow for code execution. (CVE-2021-33289)

  • In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS inode pathname is supplied in an NTFS image a heap buffer overflow can occur resulting in memory disclosure, denial of service and even code execution. (CVE-2021-35266)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
