Synopsis ========
A vulnerability was discovered in Flatpak which could allow a remote attacker to execute arbitrary code.
Background ==========
Flatpak is a Linux application sandboxing and distribution framework.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/flatpak < 1.10.0 >= 1.10.0
Description ===========
A bug was discovered in the flatpak-portal service that can allow sandboxed applications to execute arbitrary code on the host system (a sandbox escape).
Impact ======
A remote attacker could entice a user to open a specially crafted Flatpak app possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
Workaround ==========
As a workaround, this vulnerability can be mitigated by preventing the flatpak-portal service from starting, but that mitigation will prevent many Flatpak apps from working correctly. It is highly recommended to upgrade.
Resolution ==========
All Flatpak users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/flatpak-1.10.0"
