Subject: [PATCH] net: Fix OOB write in grub_net_search_config_file()
|
||||
|
||||
The function included a call to grub_strcpy() which copied data from an
|
||||
environment variable to a buffer allocated in grub_cmd_normal(). The
|
||||
grub_cmd_normal() didn't consider the length of the environment variable.
|
||||
So, the copy operation could exceed the allocation and lead to an OOB
|
||||
write. Fix the issue by replacing grub_strcpy() with grub_strlcpy() and
|
||||
pass the underlying buffers size to the grub_net_search_config_file().

Subject: [PATCH] commands/read: Fix an integer overflow when supplying more
|
||||
than 2^31 characters
|
||||
|
||||
The grub_getline() function currently has a signed integer variable "i"
|
||||
that can be overflown when user supplies more than 2^31 characters.
|
||||
It results in a memory corruption of the allocated line buffer as well
|
||||
as supplying large negative values to grub_realloc().
