CVE-2019-13106: ext4: fix out-of-bounds memset

2019-07-18T15:31:29Z

In ext4fs_read_file in ext4fs.c, a memset can overwrite the bounds of the destination memory region. This patch adds a check to disallow this. Signed-off-by: Paul Emge

ext4: gracefully fail on divide-by-0

2019-07-18T15:31:29Z

This patch checks for 0 in several ext4 headers and gracefully fails instead of raising a divide-by-0 exception. Signed-off-by: Paul Emge

CVE-2019-13104: ext4: check for underflow in ext4fs_read_file

2019-07-18T15:31:29Z

in ext4fs_read_file, it is possible for a broken/malicious file system to cause a memcpy of a negative number of bytes, which overflows all memory. This patch fixes the issue by checking for a negative length. Signed-off-by: Paul Emge

CVE-2019-13105: ext4: fix double-free in ext4_cache_read

2019-07-18T15:31:28Z

ext_cache_read doesn't null cache->buf, after freeing, which results in a later function double-freeing it. This patch fixes ext_cache_read to call ext_cache_fini instead of free. Signed-off-by: Paul Emge

ext4: add support for filesystems without JOURNAL

2019-07-18T15:31:24Z

JOURNAL is optional for EXT4 (and EXT3) filesystems, so add support for skipping it. This fixes corrupting EXT4 volumes without JOURNAL after using uboot's 'ext4write' command. Signed-off-by: Marek Szyprowski Reviewed-by: Lukasz Majewski

ext4: fix calculating inode blkcount for non-512 blocksize filesystems

2019-07-18T15:31:24Z

The block count entry in the EXT4 filesystem disk structures uses standard 512-bytes units for most of the typical files. The only exception are HUGE files, which use the filesystem block size, but those are not supported by uboot's EXT4 implementation anyway. This patch fixes the EXT4 code to use proper unit count for inode block count. This fixes errors reported by fsck.ext4 on disks with non-standard (i.e. 4KiB, in case of new flash drives) PHYSICAL block size after using 'ext4write' uboot's command.

fs: do_load: pass device path for efi payload

2019-06-20T22:26:20Z

fatload command can be used to load the EFI payload since EFI system partition is always a FAT partition. Call into EFI code from do_load() to set the device path from which the last binary was loaded. An EFI application like grub2 can’t find its configuration file without the device path set. Since device path is now set in do_load() there is no need to set it in do_load_wrapper() for the load command. Signed-off-by: Mian Yousaf Kaukab Reviewed-by: Heinrich Schuchardt
