CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:L/AC:M/Au:N/C:C/I:C/A:C
Summary:
The remote host is missing an update for the 'kernel'
Linux Distribution Package(s) announced via the referenced advisory.
Affected Versions:
kernel on CentOS 4
Technical Details:
The kernel Linux Distribution Packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* a NULL pointer dereference flaw was found in each of the following
functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and
pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could
be released by other processes before it is used to update the pipe's
reader and writer counters. This could lead to a local denial of service or
privilege escalation. (CVE-2009-3547, Important)
Users should upgrade to these updated Linux Distribution Packages, which contain a backported
patch to correct these issues. The system must be rebooted for this update
to take effect.
Recommendations:
Please install the updated Linux Distribution Packages.
Detection Type:
Linux Distribution Package
Solution Type:
Vendor Patch

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
