CVE-2009-0747  (opens in a new tab)
CWE-399  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.27.19, 2.6.28.7 or higher.

Overview

Affected versions of this package are vulnerable to Resource Management Errors. The ext4_isize function in fs/ext4/ext4.h in the Linux kernel 2.6.27 before 2.6.27.19 and 2.6.28 before 2.6.28.7 uses the i_size_high structure member during operations on arbitrary types of files, which allows local users to cause a denial of service (CPU consumption and error-message flood) by attempting to mount a crafted ext4 filesystem.
