Squashfs: add corruption check for type in squashfs_readdir()

2013-09-06T03:57:54+00:00

We read the type field from disk. This value should be sanity checked for correctness to avoid an out of bounds access when reading the squashfs_filetype_table array. Signed-off-by: Phillip Lougher

Squashfs: add corruption check in get_dir_index_using_offset()

2013-09-06T03:57:53+00:00

We read the size (of the name) field from disk. This value should be sanity checked for correctness to avoid blindly reading huge amounts of unnecessary data from disk on corruption. Note, here we're not actually reading the name into a buffer, but skipping it, and so corruption doesn't cause buffer overflow, merely lots of unnecessary amounts of data to be read.

Squashfs: fix corruption checks in squashfs_readdir()

2013-09-06T03:57:53+00:00

The dir_count and size fields when read from disk are sanity checked for correctness. However, the sanity checks only check the values are not greater than expected. As dir_count and size were incorrectly defined as signed ints, this can lead to corrupted values appearing as negative which are not trapped. Signed-off-by: Phillip Lougher

Squashfs: fix f_pos check in get_dir_index_using_offset

2012-03-10T03:01:02+00:00

One off error in the f_pos check. If f_pos is 3 or less don't bother reading the index because we're at the start of the directory, and we obviously already know where that is on disk. This eliminates an unnecessary read. Signed-off-by: Phillip Lougher
