"David Ford discovered that the IPv4 defragmentation routine did not
correctly handle oversized packets. A remote attacker could send
specially crafted traffic that would cause a system to crash, leading
to a denial of service. (The fix was included in the earlier kernels
from USN-864-1.) (CVE-2009-1298)

Akira Fujita discovered that the Ext4 'move extents' ioctl did not
correctly check permissions. A local attacker could exploit this to
overwrite arbitrary files on the system, leading to root privilege
escalation. (CVE-2009-4131).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
