A flaw was found in the way grub2 handled backspace characters entered in username and password prompts. An attacker with access to the system console could use this flaw to bypass grub2 password protection and gain administrative access to the system.
Unitrends risk assessment: None
Unitrends systems do not use grub2, but grub-0.97-93.el6.x86_64 or grub-0.97-99 for el5, which are not affected.
No action required.
