Amazon Linux 2 : emacs (ALAS-2025-2770)

high Nessus Plugin ID 232355

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of emacs installed on the remote host is prior to 27.2-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2770 advisory.

 A flaw was found in the Emacs text editor. Improper handling of custom man URI schemes allows attackers to execute arbitrary shell commands by tricking users into visiting a specially crafted website or an HTTP URL with a redirect. (CVE-2025-1244)

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

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

Solution

Run 'yum update emacs' to update your system.
