CVE Author: NIST National Vulnerability Database

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

Summary:
Check the version of kernel

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The kernel Linux Distribution Packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's splice() system call validated its parameters. On certain file systems, a local, unprivileged user could use this flaw to write past the maximum file size, and thus crash the system. (CVE-2014-7822, Moderate) Red Hat would like to thank Akira Fujita of NEC for reporting this issue. This update also fixes the following bugs: * Previously, hot-unplugging of a virtio-blk device could in some cases lead to a kernel panic, for example during in-flight I/O requests. This update fixes race condition in the hot-unplug code in the virtio_blk.ko module. As a result, hot unplugging of the virtio-blk device no longer causes the guest kernel oops when there are in-flight I/O requests. (BZ#1006536) * Before this update, due to a bug in the error-handling path, a corrupted metadata block could be used as a valid block. With this update, the error handling path has been fixed and more checks have been added to verify the metadata block. Now, when a corrupted metadata block is encountered, it is properly marked as corrupted and handled accordingly. (BZ#1034403) * Previously, an incorrectly initialized variable resulted in a random value being stored in the variable that holds the number of default ACLs, and is sent in the SET_PATH_INFO data structure. Consequently, the setfacl command could, under certain circumstances, fail with an 'Invalid argument' error. With this update, the variable is correctly initialized to zero, thus fixing the bug. (BZ#1105625) All kernel users are advised to 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.

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".
