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

    The UNIX editor Vim prior to version 9.1.0678 has a use-after-free error in argument list handling.When
    adding a new file to the argument list, this triggers `Buf*` autocommands.If in such an autocommand the
    buffer that was just opened is closed (including the window where it is shown), this causes the window
    structure to be freed which contains a reference to the argument list that we are actually modifying.Once
    the autocommands are completed, the references to the window and argument list are no longer valid and as
    such cause an use-after-free.Impact is low since the user must either intentionally add some unusual
    autocommands that wipe a buffer during creation (either manually or by sourcing a malicious plugin), but
    it will crash Vim.The issue has been fixed as of Vim patch v9.1.0678.(CVE-2024-43374)

Tenable has extracted the preceding description block directly from the EulerOS vim security advisory.

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