The version of emacs installed on the remote host is prior to 27.2-4. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1981 advisory.

    GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a     source-code file, because lib-src/etags.c uses the system C library function in its implementation of the     etags program. For example, a victim may use the etags -u * command (suggested in the etags     documentation) in a situation where the current working directory has contents that depend on untrusted     input. (CVE-2022-48337)

    An issue was discovered in GNU Emacs through 28.2. In ruby-mode.el, the ruby-find-library-file function     has a local command injection vulnerability. The ruby-find-library-file function is an interactive     function, and bound to C-c C-f. Inside the function, the external command gem is called through shell-     command-to-string, but the feature-name parameters are not escaped. Thus, malicious Ruby source files may     cause commands to be executed. (CVE-2022-48338)

    An issue was discovered in GNU Emacs through 28.2. htmlfontify.el has a command injection vulnerability.
    In the hfy-istext-command function, the parameter file and parameter srcdir come from external input, and     parameters are not escaped. If a file name or directory name contains shell metacharacters, code may be     executed. (CVE-2022-48339)

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.
