Hello Kurt, Steve, vendors, a security flaw was found in the way bootloader configuration module of Anaconda, a graphical system installer, stored password hashes when performing write of password configuration file (0755 permissions were used instead of 0700 ones). A local users could use this flaw to obtain password hashes and conduct brute force password guessing attacks (possibly leading to password circumvention, machine reboot or use of custom kernel or initrd command line parameters). Upstream patch: [1] http://git.fedorahosted.org/git/?p=anaconda.git;a=commit;h=03ef13b625cc06873a924e0610340f8489fd92df References: [2] https://bugzilla.redhat.com/show_bug.cgi?id=819031 Could you allocate a CVE identifier for this? Thank you && Regards, Jan. -- Jan iankko Lieskovsky / Red Hat Security Response Team
