Título:	CentOS Update for kernel CESA-2014:1023 centos7
Resumen:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Descripción:	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. * It was found that Linux kernel's ptrace subsystem did not properly sanitize the address-space-control bits when the program-status word (PSW) was being set. On IBM S/390 systems, a local, unprivileged user could use this flaw to set address-space-control bits to the kernel space, and thus gain read and write access to kernel memory. (CVE-2014-3534, Important) * It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. (CVE-2014-0181, Moderate) * It was found that a remote attacker could use a race condition flaw in the ath_tx_aggr_sleep() function to crash the system by creating large network traffic on the system's Atheros 9k wireless network adapter. (CVE-2014-2672, Moderate) * A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system. (CVE-2014-2673, Moderate) * A race condition flaw was found in the way the Linux kernel's mac80211 subsystem implementation handled synchronization between TX and STA wake-up code paths. A remote attacker could use this flaw to crash the system. (CVE-2014-2706, Moderate) * An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made. (CVE-2014-4667, Moderate) Red Hat would like to thank Martin Schwidefsky of IBM for reporting CVE-2014-3534, Andy Lutomirski for reporting CVE-2014-0181, and Gopal Reddy Kodudula of Nokia Siemens Networks for reporting CVE-2014-4667. This update also fixes the following bugs: * Due to a NULL pointer dereference bug in the IPIP and SIT tunneling code, a kernel panic could be triggered when using IPIP or SIT tunnels with IPsec. This update restructures the related code to avoid a NULL pointer dereference and the kernel no longer panics when using IPIP or SIT tunnels with IPsec. (BZ#1114957) * Previously, an IBM POWER8 system could terminate unexpectedly when the kernel received an IRQ while handling a transactional memory re-checkpoint critical section. This update ensures that ... Description truncated, please see the referenced URL(s) for more information. Affected Software/OS: kernel on CentOS 7 Solution: Please install the updated packages.
