Updated flatpak packages fix security vulnerability

Publication date: 23 Oct 2021
Modification date: 23 Oct 2021
Type: security
Affected Mageia releases : 8
CVE: CVE-2021-41133

Description

Flatpak apps with direct access to AF_UNIX sockets such as those used by
Wayland, Pipewire or pipewire-pulse can trick portals and other host-OS
services into treating the Flatpak app as though it was an ordinary,
non-sandboxed host-OS process, by manipulating the VFS using recent
mount-related syscalls that are not blocked by Flatpak's denylist seccomp
filter, in order to substitute a crafted /.flatpak-info or make that file
disappear entirely.
