[Bug 2012972] Re: grub2 bug preventing loading kernels

[Aleksandar Atanasovski]

** Description changed:

  Hello everyone,
  
  I found a critical bug in your latest version of grub2 (2.06-2ubuntu7.1)
- that prevents loading many types of kernel. The program hangs infinitely
- on black screen / background image when trying to load without
- displaying any kind of error message.
+ that prevents loading many types of kernel. After selecting kernel to
+ load from the menu the program hangs infinitely on black screen /
+ background image without displaying any kind of error message.
  
  I attached a proposed fix.
  
  In some kernels header size by specification can be less than "sizeof"
  header struct. In original GRUB 2.06 source code there is same condition
  which is missing in your version.
  
  You're welcome to contact me for more info,
  
  Cheers,
  
  Aleksandar
