  "details" : [ "A Use-After-Free vulnerability has been discovered in GRUB's gettext module. This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded.", "A Use-After-Free vulnerability has been discovered in GRUB's gettext module.

  "statement" : "This vulnerability has been rated as have the impact of Moderate by the Red Hat Product Security team. This decision was made based in the fact an attacker needs local or physical access to the machine, to execute the gettext command after it was unloaded. Additionally the most likely outcome from an successful attack is a Denial of Crash by leading the grub2 to crash.",
