The patch titled Subject: decompress_bunzip2: off by one in get_next_block() has been removed from the -mm tree. Its filename was decompress_bunzip2-off-by-one-in-get_next_block.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> Subject: decompress_bunzip2: off by one in get_next_block() "origPtr" is used as an offset into the bd->dbuf[] array. That array is allocated in start_bunzip() and has "bd->dbufSize" number of elements so the test here should be >= instead of >. Later we check "origPtr" again before using it as an offset so I don't know if this bug can be triggered in real life.
