It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-050 advisory.

    A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files with an unintended group ownership and with group execution and SGID     permission bits set, in a scenario where a directory is SGID and belongs to a certain group and is     writable by a user who is not a member of this group. This can lead to excessive permissions granted in     case when they should not. (CVE-2018-13405)

    A flaw was found in the QEMU virtio-fs shared file system daemon (virtiofsd) implementation. This flaw is     strictly related to CVE-2018-13405. A local guest user can create files in the directories shared by     virtio-fs with unintended group ownership in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of the group. This could allow a malicious unprivileged user     inside the guest to gain access to resources accessible to the root group, potentially escalating their     privileges within the guest. A malicious local user in the host might also leverage this unexpected     executable file created by the guest to escalate their privileges on the host system. (CVE-2022-0358)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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