CVE-2017-1000455
GuixSD prior to Git commit 5e66574a128937e7f2fcf146d146225703ccfd5d used POSIX hard links incorrectly, leading the creation of setuid executables in "the store", violating a fundamental security assumption of GNU Guix.
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
