Debian Security Advisory DSA-4984-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
October 12, 2021 https://www.debian.org/security/faq
Package : flatpak
CVE ID : CVE-2021-41133
Debian Bug : 995935
It was discovered that sandbox restrictions in Flatpak, an application
deployment framework for desktop apps, could be bypassed for a Flatpak
app with direct access to AF_UNIX sockets, by manipulating the VFS using
mount-related syscalls that are not blocked by Flatpak's denylist
seccomp filter.
Details can be found in the upstream advisory at
https://github.com/flatpak/flatpak/security/advisories/GHSA-67h7-w3jq-vh4q
For the stable distribution (bullseye), this problem has been fixed in
version 1.10.5-0+deb11u1.
We recommend that you upgrade your flatpak packages.
