1264103: CVE-2015-5281 grub2: modules built in on EFI builds that allow loading arbitrary code, circumventing secure boot
It was discovered that grub2 builds for EFI systems contained modules that were not suitable to be loaded in a Secure Boot environment. An attacker could use this flaw to circumvent the Secure Boot mechanisms and load non-verified code. Attacks could use the boot menu if no password was set, or the grub2 configuration file if the attacker has root privileges on the system.
