Related CVEs CVE-2024-39331


A vulnerability was discovered in GNU Emacs, the extensible, customisable, self-documenting display editor.

The org-link-expand-abbrev function expanded a %(…) link abbrev even when the abbrev specified an unsafe function, such as shell-command-to-string. This could lead to arbitrary code execution as soon as an Org-mode format file was opened.



For Debian 8 jessie, these problems have been fixed in version 24.4+1-5+deb8u5.

For Debian 9 stretch, these problems have been fixed in version 24.5+1-11+deb9u5.

We recommend that you upgrade your emacs24 packages.
