CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:L/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 6

Recommendations:
Please install the updated Linux Distribution Packages.

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: * Numerous reference count leaks were found in the Linux kernel's block layer I/O context handling implementation. This could allow a local, unprivileged user to cause a denial of service. (CVE-2012-0879, Moderate) * A flaw was found in the Linux kernel's cifs_lookup() implementation. POSIX open during lookup should only be supported for regular files. When non-regular files (for example, a named (FIFO) pipe or other special files) are opened on lookup, it could cause a denial of service. (CVE-2012-1090, Moderate) * It was found that the Linux kernel's register set (regset) common infrastructure implementation did not check if the required get and set handlers were initialized. A local, unprivileged user could use this flaw to cause a denial of service by performing a register set operation with a ptrace() PTRACE_SETREGSET or PTRACE_GETREGSET request. (CVE-2012-1097, Moderate) Red Hat would like to thank H. Peter Anvin for reporting CVE-2012-1097. This update also fixes several bugs and adds various enhancements. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues, and fix the bugs and add the enhancements noted in the Technical Notes. 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".
