I was looking in Debian's cairo package for fixes for other CVEs (namely
the ones that "guix lint -c cve cairo" *did* report), and noticed that
they included a fix for CVE-2020-35492.  I didn't investigate further.

While we're on the subject on issues with the CVE database, or possibly
with our linter, "guix lint -c cve" now erroneously reports:

--8<---------------cut here---------------start------------->8---
gnu/packages/gnome.scm:8434:2: gnome-shell@3.34.5: probably vulnerable to 
gnu/packages/gnome.scm:6452:2: gvfs@1.40.2: probably vulnerable to 
CVE-2019-12447, CVE-2019-12448, CVE-2019-12449
--8<---------------cut here---------------end--------------->8---

All of these are incorrect.

* CVE-2019-3820 was fixed long before GNOME 3.34 came out, and I've
  verified that the commit that fixes it is included in

    commit f0a7395b3006360905ccdc642982f9fc67378927
    Author: Ray Strode <>
    Date:   Wed Jan 23 15:59:15 2019 -0500

    shellActionModes: disable POPUP keybindings in unlock screen

* CVE-2019-12447, CVE-2019-12448, and CVE-2019-12449 are fixed in
  gvfs-1.40.2, according to its NEWS file:

--8<---------------cut here---------------start------------->8---
