CVE-2017-15131 · MEDIUM Severity

AV:L/AC:L/AU:N/C:P/I:P/A:P

It was found that system umask policy is not being honored when creating XDG user directories, since Xsession sources xdg-user-dirs.sh before setting umask policy. This only affects xdg-user-dirs before 0.15.5 as shipped with Red Hat Enterprise Linux.
