5
6The grub_extcmd_dispatcher() calls grub_arg_list_alloc() to allocate
7a grub_arg_list struct but it does not verify the allocation was successful.
8In case of failed allocation the NULL state pointer can be accessed in
9parse_option() through grub_arg_parse() which may lead to a security issue.

7number parsed by read_number(). Later direct arithmetic calculation like
8"namesize + 1" and "linksize + 1" may exceed the maximum value of
9grub_size_t leading to heap OOB write. This patch fixes the issue by
10using grub_add() and checking for an overflow.

6grub_strcpy() was used to copy a symlink name from the filesystem

4Subject: [PATCH] fs/hfsplus: Set a grub_errno if mount fails
5
6It was possible for mount to fail but not set grub_errno. This led to
7a possible double decrement of the module reference count if the NULL
8page was mapped.
9
10Fixing in general as a similar bug was fixed in commit 61b13c187
11(fs/hfsplus: Set grub_errno to prevent NULL pointer access) and there
12are likely more variants around.
