Updated coreutils packages fix security vulnerabilities

Publication date: 08 Jan 2019
Type: security
Affected Mageia releases : 6
CVE: CVE-2017-18018 , CVE-2018-17942


A flaw was found in GNU Coreutils through 8.29 in chown-core.c. The
functions chown and chgrp do not prevent replacement of a plain file
with a symlink during use of the POSIX "-R -L" options, which allows
local users to modify the ownership of arbitrary files by leveraging a
race condition (CVE-2017-18018).

A flaw was found in Gnulib before 2018-09-23. The convert_to_decimal
function in vasnprintf.c has a heap-based buffer overflow because memory
is not allocated for a trailing '\0' character during %f processing
