GNU GRUB

GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project. GRUB is the reference implementation of the Free Software Foundation’s Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular operating system’s partitions.

GRUB’s function is to take over from BIOS at boot time, load itself, load the Linux kernel into memory, and then turn over execution to the kernel. GNU GRUB is predominantly used for Unix-like systems. The GNU operating system uses GNU GRUB as its boot loader, as do most Linux distributions and the Solaris operating system on x86 systems, starting with the Solaris 10 1/06 release.

 

We are currently looking for the following items in GNU GRUB:

  • Code/Command execution vulnerability
  • Privileges escalation

*Found something that isn’t on this list? We may still buy it!
