Debian DSA-5360-1 : emacs - security update

critical Nessus Plugin ID 171900

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5360 advisory.

Xi Lu discovered that missing input sanitising in Emacs (in etags, the Ruby mode and htmlfontify) could result in the execution of arbitrary shell commands. For the stable distribution (bullseye), these problems have been fixed in version 1:27.1+1-3.1+deb11u2. We recommend that you upgrade your emacs packages. For the detailed security status of emacs please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/emacs

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the emacs packages.

For the stable distribution (bullseye), these problems have been fixed in version 1
