If I can write to files you own, it doesn't matter if there's a
directory in the PATH or not. I can write this to your .bash_profile:
/bin/mkdir $HOME/.bin 2> /dev/null
echo 'echo "i could rm -rf ~/ here"' > $HOME/.bin/mkdir
chmod +x $HOME/.bin/mkdir
PATH=$HOME/.bin:$PATH
you can do this and that - but that's no valid argumentation
doing bad things in default setups and *at least* do not
place *hidden* diretories there, ther is a good reason why
software like rkhunter alerts if you have hidden directories
somewhere in /usr/bin/
Some kind of reference for the bad in having a well-known, hidden directory in
the path?
the *writeable for the user* is the problem
Any reference for this problem?
what about consider the implications?
do you really need a written reference for any security relevant fact?
i can write one for you if you prefer links :-)
Well, the question is really if someone else out there share your concerns
about this
anybody with interests in security
https://www.google.at/search?q=ssh+chroot+why+needs+the+home+directory+to+be+owned+by+root
http://binblog.info/2008/04/06/openssh-chrooted-sftp-eg-for-webhosting/
However, the chroot destination must not be owned by the user for security
reasons
So you are arguing that $HOME should be owned by root?! An interesting
subject, but isn't it a little off-topic, deserving a separate thread?
