Title:	CentOS Update for kernel CESA-2014:0740 centos5
Summary:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory. Vulnerability Insight: The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important) * It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use this flaw to obtain information about the kernel heap arrangement. (CVE-2014-1738, Low) Note: A local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system. * A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. (CVE-2013-7339, Moderate) Red Hat would like to thank Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738. This update also fixes the following bugs: * A bug in the futex system call could result in an overflow when passing a very large positive timeout. As a consequence, the FUTEX_WAIT operation did not work as intended and the system call was timing out immediately. A backported patch fixes this bug by limiting very large positive timeouts to the maximal supported value. (BZ#1091832) * A new Linux Security Module (LSM) functionality related to the setrlimit hooks should produce a warning message when used by a third party module that could not cope with it. However, due to a programming error, the kernel could print this warning message when a process was setting rlimits for a different process, or if rlimits were modified by another than the main thread even though there was no incompatible third party module. This update fixes the relevant code and ensures that the kernel handles this warning message correctly. (BZ#1092869) * Previously, the kernel was unable to detect KVM on system boot if the Hyper-V emulation was enabled. A patch has been applied to ensure that both KVM and Hyper-V hypervisors are now correctly detected during system boot. (BZ#1094152) * A function in the RPC code responsible for verifying whether cached credentials match the current process did not perform the check correctly. The code checked only whether the groups in the current process credentials appear in the same order as i ... Description truncated, please see the referenced URL(s) for more information. Affected Software/OS: kernel on CentOS 5 Solution: Please install the updated packages. CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
