Bug#895990: gdm3: memory leak (known upstream)

[Dennis Grunert]

Package: gdm3
Version: 3.22.3-3+deb9u1
Severity: critical
Tags: upstream
Justification: breaks the whole system

Dear Maintainer,

the gdm3 process has a memory leak which continuously consumes more and
more memory until the OOM killer renders the system unusable. Therefore,
this bug was tagged as critical. Up to 10 GB memory usage of gdm3 were
observered until we killed the process to prevent further problems. From
our 59 identical systems, 3 suffered from this leak in the past days.

This bug is known upstream, see
https://bugs.launchpad.net/gnome-shell/+bug/1672297

Comment 66 of the above bug report includes fixes for the upstream
packages. Please backport them to Debian stable.

Kind regards

Dennis Grunert
