Description:
Multiple integer signedness errors in the sg_scsi_ioctl function in
scsi_ioctl.c for Linux 2.6.x allow local users to read or modify kernel
memory via negative integers in arguments to the scsi ioctl, which
bypass a maximum length check before calling the copy_from_user and
copy_to_user functions.
Notes:
jmm> The 2.4.27 version, scsi_ioctl_send_command(), is not affected, as
jmm> intlen and outlen are unsigned ints
