Subject: CVE Request -- coreutils -- unsafe temporary directory location use

Hi Steve, vendors,

   Jim Meyering reported a flaw in coreutils in the way, its
"distcheck" Makefile rule used to set up a temporary directory
location to be used later for performing its own tasks.
This might allow local attacker to conduct symlink attacks or
potentially execute arbitrary code under certain circumstances.

Thanks && Regards, Jan.
