Package: nheko
Version: 0.11.3-2
Severity: critical
Tags: upstream
Justification: breaks unrelated software
X-Debbugs-Cc: [email protected]

If Ungoogled Chromium ver 112 is running when Nheko is launched, the
UC job freezes. No user i/o is accepted.. it becomes like a kind of
software brick. UC cannot even be closed, only killed from the CLI.

If UC is left alone in the frozen state until Nheko exits, then Nheko
brings UC down with it.

This report is tagged as /critical/ because it disasterously impacts
another unrelated application. It’s also a local security problem
because different X or Wayland apps should not have the capability of
interfering with each other like this. But I did not tag the report as
“security” because it’s not the sort of vuln that remote attackers
could easily exploit without chaining other exploits. 

FWIW, the testing was done on a system running Wayland, Sway, and X
Wayland.

Also note that Ungoogled Chromium is not in official Debian repos. But
Chromium is, so this defect likely impacts Chromium. I have not tested
that myself but if someone confirms it, then this bug should be tagged
as affecting Chromium.
