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

  - 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     ctags program. For example, a victim may use the 'ctags *' command (suggested in the ctags documentation)     in a situation where the current working directory has contents that depend on untrusted input.
    (CVE-2022-45939)

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 version of emacs installed on the remote host is prior to 24.3-20.25. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1712 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     ctags program. For example, a victim may use the ctags * command (suggested in the ctags documentation)     in a situation where the current working directory has contents that depend on untrusted input.
    (CVE-2022-45939)

    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. 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.

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