CentOS Update for kernel CESA-2011:0833 centos5 x86_64

Published: 2012-07-30 11:39:50
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/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 5

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: * A flaw in the dccp_rcv_state_process() function could allow a remote attacker to cause a denial of service, even when the socket was already closed. (CVE-2011-1093, Important) * Multiple buffer overflow flaws were found in the Linux kernel's Management Module Support for Message Passing Technology (MPT) based controllers. A local, unprivileged user could use these flaws to cause a denial of service, an information leak, or escalate their privileges. (CVE-2011-1494, CVE-2011-1495, Important) * A missing validation of a null-terminated string data structure element in the bnep_sock_ioctl() function could allow a local user to cause an information leak or a denial of service. (CVE-2011-1079, Moderate) * Missing error checking in the way page tables were handled in the Xen hypervisor implementation could allow a privileged guest user to cause the host, and the guests, to lock up. (CVE-2011-1166, Moderate) * A flaw was found in the way the Xen hypervisor implementation checked for the upper boundary when getting a new event channel port. A privileged guest user could use this flaw to cause a denial of service or escalate their privileges. (CVE-2011-1763, Moderate) * The start_code and end_code values in '/proc/[pid]/stat' were not protected. In certain scenarios, this flaw could be used to defeat Address Space Layout Randomization (ASLR). (CVE-2011-0726, Low) * A missing initialization flaw in the sco_sock_getsockopt() function could allow a local, unprivileged user to cause an information leak. (CVE-2011-1078, Low) * A missing validation of a null-terminated string data structure element in the do_replace() function could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1080, Low) * A buffer overflow flaw in the DEC Alpha OSF partition implementation in the Linux kernel could allow a local attacker to cause an information leak by mounting a disk that contains specially-crafted partition tables. (CVE-2011-1163, Low) * Missing validations of null-terminated string data structure elements in the do_replace(), compat_do_replace(), do_ipt_get_ctl(), do_ip6t_get_ctl(), and do_arpt_get_ctl() functions could allow a local user who has the CAP_NET_ADMIN capability to cause an information leak. (CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, Low) * A heap overflow flaw in the Linux kernel's EFI GUID Partition ... Description truncated, please see the referenced URL(s) for more information.

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".
