Binary package hint: firefox
After running apt-get upgrade in the last 24 hours, I noticed that the
backup of my home directory using backup2l -- an incremental backup
program -- jumped to have a gigabyte for one days' increment. Alarmed
by this, I investigated and seems that NSPlugin Viewer is writing the
following lines to $HOME/.xsession-errors at least once every second and
as such is rapidly filling the /home partition:
$ ls -l .xession-errors
-rw------- 1 morse morse 610290736 2011-02-17 10:44 .xsession-errors
this file is normally 32-64k or such, and in less than 24 hours is now
610MB, entirely due to these identical entries:
*** NSPlugin Viewer ***

once i ran:
$ pkill -9 -f npview
the file stopped growing.
I am marking this bug as a security vulnerability because I believe it
needs immediate attention and I know of no other way of informing
canonical of the urgency of this matter. While technical not a security
concern, runaway processes like this that fill up partitions can make
machines and servers unusable. My apologies in advance if this was not
the appropriate way to report this, but I'd rather error on the side of
being a bit alarmist about this because, if this problem isn't somehow
specific to my machine -- which I tend to doubt, because nothing has
changed in my usage, installed programs, etc. other than running apt-get
upgrade -- then a lot of less technical users could be very adversely
affected. As such, I feel important that someone look into this
quickly.
