Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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).

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
