  "description": "In the Linux kernel, the following vulnerability has been resolved:  ntfs: check overflow when iterating ATTR_RECORDs  Kernel iterates over ATTR_RECORDs in mft record in ntfs_attr_find().  Because the ATTR_RECORDs are next to each other, kernel can get the next ATTR_RECORD from end address of current ATTR_RECORD, through current ATTR_RECORD length field.  The problem is that during iteration, when kernel calculates the end address of current ATTR_RECORD, kernel may trigger an integer overflow bug in executing \u0060a = (ATTR_RECORD*)((u8*)a \u002B le32_to_cpu(a-\u003Elength))\u0060.  This may wrap, leading to a forever iteration on 32bit systems.  This patch solves it by adding some checks on calculating end address of current ATTR_RECORD during iteration.",
