"This update includes a security fix for CVE-2020-10737. Additionally,

From 0.34.6 :

  - update license on src/buffer.h

  - changes '/var/run' to '/run' in systemd service file
    (Orion Poplawski, #1834511)

From 0.34.5 :

  - apply patch from Matthias Gerstner of the SUSE security
    team to fix a possible race condition in the mkhomedir
    helper (noted above, this fixes CVE-2020-10737)

  - only process SELinux contexts if SELinux is not disabled
    (Alexander Bokovoy, #1828855)

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
