    Package        : emacs     Version        : 1:27.1+1-3.1+deb11u6     CVE ID         : CVE-2023-28617 CVE-2024-53920 CVE-2025-1244     Debian Bug     : 1033342 1088690 1098255

    Multiple vulnerabilities were discovered in GNU Emacs, the extensible,     customisable, self-documenting, real-time display editor.

    CVE-2023-28617

        Improper handling of file or directory names containing shell         metacharacters in the ob-latex Lisp library could allow the         execution of attacker-controlled code.

    CVE-2024-53920

        Several ways to trigger arbitrary code execution were discovered in         Emacs's support for editing files in its own dialect of Lisp.
        These include arbitrary code execution upon opening an otherwise         innocent-looking file, with any (or no) file extension, for editing.

    CVE-2025-1244

        Improper handling of custom 'man' URI schemes could allow an         attacker to execute arbitrary shell commands by tricking users into         visiting a specially crafted website, or an HTTP URL with a         redirect.

    For Debian 11 bullseye, these problems have been fixed in version     1:27.1+1-3.1+deb11u6.

    We recommend that you upgrade your emacs packages.

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In elisp-mode.el in GNU Emacs before 30.1, a user who chooses to invoke elisp-completion-at-point (for     code completion) on untrusted Emacs Lisp source code can trigger unsafe Lisp macro expansion that allows     attackers to execute arbitrary code. (This unsafe expansion also occurs if a user chooses to enable on-     the-fly diagnosis that byte compiles untrusted Emacs Lisp source code.) (CVE-2024-53920)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:4392-1 advisory.

    - CVE-2024-53920: Fixed arbitrary code execution via Lisp macro expansion (bsc#1233894)

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

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

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5871 advisory.

    Package        : emacs     CVE ID         : CVE-2024-53920 CVE-2025-1244

    Two security vulnerabilities were discovered in Emacs:

    CVE-2024-53920

        Elisp byte-compilation ('elisp-flymake-byte-compile') in the Flymake         mode is now disabled for untrusted files.

    CVE-2025-1244

        An incomplete escaping of shell meta characters in the man reader         component could potentially result in the execution of arbitrary         shell commands. Discovered by Maxim Nikulin.

    For the stable distribution (bookworm), these problems have been fixed in     version 1:28.2+1-15+deb12u4.

    We recommend that you upgrade your emacs packages.
