+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().
