CentOS Update for kernel CESA-2015:0102 centos7

Published: 2015-01-30 04:20:12
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

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 SCTP implementation validated INIT chunks when performing Address Configuration Change (ASCONF). A remote attacker could use this flaw to crash the system by sending a specially crafted SCTP packet to trigger a NULL pointer dereference on the system. (CVE-2014-7841, Important) * A race condition flaw was found in the way the Linux kernel's mmap(2), madvise(2), and fallocate(2) system calls interacted with each other while operating on virtual memory file system files. A local user could use this flaw to cause a denial of service. (CVE-2014-4171, Moderate) * A NULL pointer dereference flaw was found in the way the Linux kernel's Common Internet File System (CIFS) implementation handled mounting of file system shares. A remote attacker could use this flaw to crash a client system that would mount a file system share from a malicious server. (CVE-2014-7145, Moderate) * 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) * It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel's ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-5471, CVE-2014-5472, Low) Red Hat would like to thank Akira Fujita of NEC for reporting the CVE-2014-7822 issue. The CVE-2014-7841 issue was discovered by Liu Wei of Red Hat. This update also fixes the following bugs: * Previously, a kernel panic could occur if a process reading from a locked NFS file was killed and the lock was not released properly before the read operations finished. Consequently, the system crashed. The code handling file locks has been fixed, and instead of halting, the system now emits a warning about the unreleased lock. (BZ#1172266) * A race condition in the command abort handling logic of the ipr device driver could cause the kernel to panic when the driver received a response to an abort command prior to receiving other responses to the aborted command due to the support for multiple interrupts. With this update, the abort handler waits for the aborted command's responses first before completing an abort operation. (BZ#1162734) * Previously, a ...

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".
