CVE-2024-53920 (GCVE-0-2024-53920)
Vulnerability from nvd – Published: 2024-11-27 00:00 – Updated: 2025-11-03 20:48
VLAI?
Summary
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-2022-48338 (GCVE-0-2022-48338)
Vulnerability from nvd – Published: 2023-02-20 00:00 – Updated: 2025-03-18 15:21
VLAI?
Summary
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.
Severity ?

CVE-2022-48337 (GCVE-0-2022-48337)
Vulnerability from nvd – Published: 2023-02-20 00:00 – Updated: 2025-03-18 15:30
VLAI?
Summary
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-2017-14482 (GCVE-0-2017-14482)
Vulnerability from nvd – Published: 2017-09-14 16:00 – Updated: 2024-08-05 19:27
VLAI?
Summary
GNU Emacs before 25.3 allows remote attackers to execute arbitrary code via email with crafted "Content-Type: text/enriched" data containing an x-display XML element that specifies execution of shell commands, related to an unsafe text/enriched extension in lisp/textmodes/enriched.el, and unsafe Gnus support for enriched and richtext inline MIME objects in lisp/gnus/mm-view.el. In particular, an Emacs user can be instantly compromised by reading a crafted email message (or Usenet news article).
Severity ?
No CVSS data available.

Summary
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.)

VLAI?
Summary
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 (GCVE-0-2022-48338)
Vulnerability from cvelistv5 – Published: 2023-02-20 00:00 – Updated: 2025-03-18 15:21
VLAI?
Summary
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-2022-45939 (GCVE-0-2022-45939)
Vulnerability from cvelistv5 – Published: 2022-11-28 00:00 – Updated: 2025-04-28 18:12
VLAI?
Summary
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.

In particular, an Emacs user can be instantly compromised by reading a crafted email message (or Usenet news article).
