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.
