According to the versions of the squashfs-tools package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different     vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link     and then contents under the same filename in a filesystem can cause unsquashfs to first create the     symbolic link pointing outside the expected directory, and then the subsequent write operation will cause     the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)

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.

  - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different     vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link     and then contents under the same filename in a filesystem can cause unsquashfs to first create the     symbolic link pointing outside the expected directory, and then the subsequent write operation will cause     the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)

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

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.101026 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)

  - EDK2's Network Package is susceptible to a buffer overflow vulnerability when processing DNS Servers     option from a DHCPv6 Advertise message. This vulnerability can be exploited by an attacker to gain     unauthorized access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
    (CVE-2023-45234)

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     KeyTrap issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - close_altfile in filename.c in less before 606 omits shell_quote calls for LESSCLOSE. (CVE-2022-48624)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of AHV installed on the remote host is prior to 20230302.102005. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20230302.102001 advisory.

  - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different     vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link     and then contents under the same filename in a filesystem can cause unsquashfs to first create the     symbolic link pointing outside the expected directory, and then the subsequent write operation will cause     the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)

  - linux-pam (aka Linux PAM) before 1.6.0 allows attackers to cause a denial of service (blocked login     process) via mkfifo because the openat call (for protect_dir) lacks O_DIRECTORY. (CVE-2024-22365)

  - An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7,     3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks     during cleanup of permissions-related errors. This means users which can run privileged programs are     potentially able to modify permissions of files referenced by symlinks in some circumstances.
    (CVE-2023-6597)

  - An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and     3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip     format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile     module reject zip archives which overlap entries in the archive. (CVE-2024-0450)

  - The DNS message parsing code in `named` includes a section whose computational complexity is overly high.
    It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive     CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative     servers and recursive resolvers. This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through     9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1     through 9.18.21-S1. (CVE-2023-4408)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
