Usernames on multiple operating systems (especially ones which are AD-joined) support "." in [long] usernames. Unfortunately, userspec.c treats "." like a user/group separator for unclear legacy reasons. This is very problematic behavior that can cause very unportable unexpected results in consumers which leverage the API, like chown(1).

Say, for instance, someone introduced a user, root.wheel, then tried to chown the file as root.wheel -- it would actually chown the file to user=root, group=wheel, which is unexpected, instead of chowning it to a user named root.wheel.

If an attacker was aware of this caveat and there was a program run as root or had superuser permissions to set file ownership and the system had a user named root.wheel, which sanitized the input to ensure that the user first existed before passing the string to chown(1), files could be setuid to allow permissions to root:wheel, and thus could be abused by the attackers to run the intercepted program with superuser privileges.

Dear all,

I am trying to compile buildroot for riscv64, but I am getting many errors. I don't know how to resolve this error.

Error:

Can any one please help me regarding above error.

Hi,
for spice-server project we import the top/maint.mk file however we have an issue with these lines:

# Prevent programs like 'sort' from considering distinct strings to be equal.
# Doing it here saves us from having to set LC_ALL elsewhere in this file.
export LC_ALL = C

specifically this affect a2x program (written in Python) which think that the encoding of some files is not utf-8 failing to compile documentation.

For more information see https://gitlab.freedesktop.org/spice/spice/issues/35.

What do you think about changing LC_ALL to LC_COLLATE?

Which one is better this or git://git.sv.gnu.org/gnulib.git and what's the difference ?

Sorry for being pedantic but according to its header, file tests/test-safe-alloc.c is under LGPL-3.1+ -- clearly a typo but strictly speaking it is impossible to comply until such license is published, if ever. :)
