According to the versions of the libarchive packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - An improper link resolution flaw while extracting an archive can lead to changing the access control list     (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would     trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL     of a file on the system and gain more privileges. (CVE-2021-23177)

  - An improper link resolution flaw can occur while extracting an archive leading to changing modes, times,     access control lists, and flags of a file outside of the archive. An attacker may provide a malicious     archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker     may use this flaw to gain more privileges in a system. (CVE-2021-31566)

A local attacker     may use this flaw to gain more privileges in a system. (CVE-2021-31566)

  - In libarchive before 3.6.2, the software does not check for an error after calling calloc function that     can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference.
    NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: In     rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it,     then writing or reading memory is possible, which may lead to code execution. (CVE-2022-36227)

This     attack appears to be exploitable via the victim opening a specially crafted 7zip file.

    CVE-2019-1000020:
    libarchive version commit 5a98dcf8a86364b3c2c469c85b93647dfb139961 onwards (version v2.8.0 onwards)     contains a CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in ISO9660     parser, archive_read_support_format_iso9660.c, read_CE()/parse_rockridge() that can result in DoS by     infinite loop. This attack appears to be exploitable via the victim opening a specially crafted ISO9660     file.

    CVE-2019-18408:
    archive_read_format_rar_read_data in archive_read_support_format_rar.c in libarchive before 3.4.0 has a     use-after-free in a certain ARCHIVE_FAILED situation, related to Ppmd7_DecodeSymbol.

    CVE-2019-19221:
    In Libarchive 3.4.0, archive_wstring_append_from_mbs in archive_string.c has an out-of-bounds read because     of an incorrect mbrtowc or mbtowc call. For example, bsdtar crashes via a crafted archive.

    CVE-2021-23177:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

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

  - An improper link resolution flaw while extracting an archive can lead to changing the access control list     (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would     trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL     of a file on the system and gain more privileges. (CVE-2021-23177)

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