The rose_parse_ccitt function in net/rose/rose_subr.c in the Linux
kernel before 2.6.39 does not validate the FAC_CCITT_DEST_NSAP and
FAC_CCITT_SRC_NSAP fields, which allows remote attackers to (1) cause
a denial of service (integer underflow, heap memory corruption, and
panic) via a small length value in data sent to a ROSE socket, or (2)
conduct stack-based buffer overflow attacks via a large length value
in data sent to a ROSE socket.
