Title:	RedHat Security Advisory RHSA-2010:0380
Summary:	NOSUMMARY
Description:	Description: The remote host is missing updates announced in advisory RHSA-2010:0380. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: * a race condition was found in the mac80211 implementation, a framework used for writing drivers for wireless devices. An attacker could trigger this flaw by sending a Delete Block ACK (DELBA) packet to a target system, resulting in a remote denial of service. Note: This issue only affected users on 802.11n networks, and that also use the iwlagn driver with Intel wireless hardware. (CVE-2009-4027, Important) * a use-after-free flaw was found in the tcp_rcv_state_process() function in the Linux kernel TCP/IP protocol suite implementation. If a system using IPv6 had the IPV6_RECVPKTINFO option set on a listening socket, a remote attacker could send an IPv6 packet to that system, causing a kernel panic (denial of service). (CVE-2010-1188, Important) * a flaw was found in the gfs2_lock() implementation. The GFS2 locking code could skip the lock operation for files that have the S_ISGID bit (set-group-ID on execution) in their mode set. A local, unprivileged user on a system that has a GFS2 file system mounted could use this flaw to cause a kernel panic (denial of service). (CVE-2010-0727, Moderate) * a divide-by-zero flaw was found in the ext4 file system code. A local attacker could use this flaw to cause a denial of service by mounting a specially-crafted ext4 file system. (CVE-2009-4307, Low) Bug fixes: * if a program that calls posix_fadvise() were compiled on x86, and then run on a 64-bit system, that program could experience various problems, including performance issues and the call to posix_fadvise() failing, causing the program to not run as expected or even abort. With this update, when such programs attempt to call posix_fadvise() on 64-bit systems, sys32_fadvise64() is called instead, which resolves this issue. This update also fixes other 32-bit system calls that were mistakenly called on 64-bit systems (including systems running the kernel-xen kernel). (BZ#569597) * on some systems able to set a P-State limit via the BIOS, it was not possible to set the limit to a higher frequency if the system was rebooted while a low limit was set: /sys/devices/system/cpu/cpu[x]/cpufreq/scaling_max_freq would retain the low limit in these situations. With this update, limits are correctly set, even after being changed after a system reboot. (BZ#569727) * certain Intel ICH hardware (using the e1000e driver) has an NFS filtering capability that did not work as expected, causing memory corruption, which could lead to kernel panics, or other unexpected behavior. In a reported case, a panic occurred when running NFS connection tests. This update resolves this issue by disabling the filtering capability. (BZ#569797) * if open(/proc/[PID]/[xxxx]) was called at the same time the process was exiting, the call would fail with an EINVAL error (an incorrect error for this situation). With this update, the correct error, ENOENT, is returned in this situation. (BZ#571362) * multiqueue is used for transmitting data, but a single queue transmit ON/OFF scheme was used. This led to a race condition on systems with the bnx2x driver in situations where one queue became full, but not stopped, and the other queue enabled transmission. With this update, only a single queue is used. (BZ#576951) * the /proc/sys/vm/mmap_min_addr tunable helps prevent unprivileged users from creating new memory mappings below the minimum address. The sysctl value for mmap_min_addr could be changed by a process or user that has an effective user ID (euid) of 0, even if the process or user does not have the CAP_SYS_RAWIO capability. This update adds a capability check for the CAP_SYS_RAWIO capability before allowing the mmap_min_addr value to be changed. (BZ#577206) Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
