|The mremap system call (do_mremap) in Linux kernel 2.4.x before
2.4.21, and possibly other versions before 2.4.24, does not properly
perform bounds checks, which allows local users to cause a denial of
service and possibly gain privileges by causing a remapping of a
virtual memory area (VMA) to create a zero length VMA, a different
vulnerability than CAN-2004-0077.
