Published: 2011-08-09 06:20:34
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:L/AC:M/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 5

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: * An integer overflow flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2010-4649, Important) * A race condition in the way new InfiniBand connections were set up could allow a remote user to cause a denial of service. (CVE-2011-0695, Important) * A flaw in the Stream Control Transmission Protocol (SCTP) implementation could allow a remote attacker to cause a denial of service if the sysctl 'net.sctp.addip_enable' variable was turned on (it is off by default). (CVE-2011-1573, Important) * Flaws in the AGPGART driver implementation when handling certain IOCTL commands could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1745, CVE-2011-2022, Important) * An integer overflow flaw in agp_allocate_memory() could allow a local, unprivileged user to cause a denial of service or escalate their privileges. (CVE-2011-1746, Important) * A flaw allowed napi_reuse_skb() to be called on VLAN (virtual LAN) packets. An attacker on the local network could trigger this flaw by sending specially-crafted packets to a target system, possibly causing a denial of service. (CVE-2011-1576, Moderate) * An integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) * A flaw in the way the Xen hypervisor implementation handled CPUID instruction emulation during virtual machine exits could allow an unprivileged guest user to crash a guest. This only affects systems that have an Intel x86 processor with the Intel VT-x extension enabled. (CVE-2011-1936, Moderate) * A flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service (infinite loop). (CVE-2011-2213, Moderate) * A missing initialization flaw in the XFS file system implementation could lead to an information leak. (CVE-2011-0711, Low) * A flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to cause an information leak. (CVE-2011-1044, Low) * A missing validation check was found in the signals implementation. A local, unprivileged user could use this flaw to send signals via the sigqueueinfo system call, with the si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. Note: This flaw does not allow existing permission chec ... 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".
