Fedora 44 : emacs (2026-b4d966ae0a)

high Nessus Plugin ID 334450

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-b4d966ae0a advisory.

 This mitigates a vulnerability that allowed a specially crafted file to trigger execution of attacker- controlled arbitrary Emacs Lisp code immediately when the file is visited in Emacs (before the file's malicious contents are even displayed). https://debbugs.gnu.org/cgi/bugreport.cgi?bug=80574

Tenable has extracted the preceding description block directly from the Fedora 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

Update the affected 1:emacs package.
