Bug#336214: gdm ignores user and system umask settings

[Benoît Dejean]

Package: gdm
Version: 2.6.0.8-1
Severity: normal

Hi,
	it looks like gdm ignores both system-wide umask settings
(from /etc/login.defs) and user settings (in ~/.<myshell>rc/profile file).
This is surpringly dangerous. Then desktop application uses gdm default 022 
as umask. I think this has to be fixed upstream but if this bug is confirmed,
i think users need to be aware of this problem and use workaround if needed.

Thanks.
