Debian 11: DLA-4069-1 Critical: emacs code execution threats

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.
