CentOS Update for kernel CESA-2010:0606 centos4 i386

Published: 2010-08-30 14:59:25
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:C/I:C/A:C

Summary:
Check for the Version of kernel

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 flaw was found in the CIFSSMBWrite() function in the Linux kernel Common Internet File System (CIFS) implementation. A remote attacker could send a specially-crafted SMB response packet to a target CIFS client, resulting in a kernel panic (denial of service). (CVE-2010-2248, Important) * buffer overflow flaws were found in the Linux kernel's implementation of the server-side External Data Representation (XDR) for the Network File System (NFS) version 4. An attacker on the local network could send a specially-crafted large compound request to the NFSv4 server, which could possibly result in a kernel panic (denial of service) or, potentially, code execution. (CVE-2010-2521, Important) This update also fixes the following bug: * the rpc_call_async() function in the SUN Remote Procedure Call (RPC) subsystem in the Linux kernel had a reference counting bug. In certain situations, some Network Lock Manager (NLM) messages may have triggered this bug on NFSv2 and NFSv3 servers, leading to a kernel panic (with " kernel BUG at fs/lockd/host.c:[xxx]!" logged to " /var/log/messages" ). (BZ#612962) Users should upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Recommendations:
Please Install the Updated Packages.

Detection Type:
Linux Distribution Package

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".
