Alpine: multiple flatpak packages: security update to 1.12.5-r0

medium Tenable Cloud Security Plugin ID 404477

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Flatpak is a Linux application sandboxing and distribution framework. A path traversal vulnerability
 affects versions of Flatpak prior to 1.12.3 and 1.10.6. flatpak-builder applies `finish-args` last in the
 build. At this point the build directory will have the full access that is specified in the manifest, so
 running `flatpak build` against it will gain those permissions. Normally this will not be done, so this is
 not problem. However, if `--mirror-screenshots-url` is specified, then flatpak-builder will launch
 `flatpak build --nofilesystem=host appstream-utils mirror-screenshots` after finalization, which can lead
 to issues even with the `--nofilesystem=host` protection. In normal use, the only issue is that these
 empty directories can be created wherever the user has write permissions. However, a malicious application
 could replace the `appstream-util` binary and potentially do something more hostile. This has been
 resolved in Flatpak 1.12.3 and 1.10.6 by changing the behaviour of `--nofilesystem=home` and
 `--nofilesystem=host`. (CVE-2022-21682)
