------------------------------------------------------------------------- Debian LTS Advisory DLA-4069-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Sean Whitton February 27, 2025 https://wiki.debian.org/LTS ------------------------------------------------------------------------- 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.
