The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2023:3104 advisory.

  - A flaw was found in the Emacs text editor. Processing a specially crafted org-mode code with the org-     babel-execute:latex function in ob-latex.el can result in arbitrary command execution. This CVE exists     because of a CVE-2023-28617 security regression for the emacs package in Red Hat Enterprise Linux 8.8 and     Red Hat Enterprise Linux 9.2. (CVE-2023-2491)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2023:0154 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2022-48337:
    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-2022-48338:
    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-2022-48339:
    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-2023-2491:
    A flaw was found in the Emacs text editor. Processing a specially crafted org-mode code with the org-     babel-execute:latex function in ob-latex.el can result in arbitrary command execution. This CVE exists     because of a CVE-2023-28617 security regression for the emacs package in Red Hat Enterprise Linux 8.8 and     Red Hat Enterprise Linux 9.2.

    CVE-2023-28617:
    org-babel-execute:latex in ob-latex.el in Org Mode through 9.6.1 for GNU Emacs allows attackers to execute     arbitrary commands via a file name or directory name that contains shell metacharacters.
